Dweller is the first roguelike created for java enabled cellphones. The project was announced and a first alpha version was released on the 12th of August 2003.

Description

Dweller is a fantasy roguelike for Java enabled cellphones. A version for desktop computers also exist, but the main focus of development is for mobile platforms. Some of its features are:

• Three player classes, the Warrior, the Wizard and the Ranger
• A simple end goal, kill the Goblin king!
• Random dungeons (with optional persistence)
• Several different monsters (Goblins, Orcs, Trolls, Oozes, Vampires, Rats, Bats, Skeletons and so on) with simple AI
• Items, item enchants and named artifact items
• Merchant to buy and sell items from/to
• Inventory and equipment
• Spells and ranged weapons
• FOV
• Save/Load
• Old school pixel graphics and animations
• Touch screen support

Dweller is designed to run on any MIDP2 or Android OS 1.5+ enabled handset. Older versions also work on MIDP1 handsets, but in 2009 MIDP1 support was abandoned.

How to Play

Note: All keys can be redefined within the game to better suit your handset. Since mobile phones have a somewhat limited set of input options Dweller also has a rather simplistic interface and way of game play. The game offers the following set of commands:

• Movement (one command for each direction)
• Interact (pick something up, open a chest, ranged attack on a targeted monster, descend stairs etc)
• Targeting (look around on the map and target distant monsters)
• Cycle target (only while in targeting mode)
• Exit/Cancel (closes a menu or leaves targeting mode)
• Inventory
• Main Menu

Movement

Use the Movement commands to move. If you have a touch screen enabled handset just tap on the screen in the direction you wish to move. Note: Orthogonal and diagonal moves take the same amount of time.

Combat

Move into monsters to attack them. Use targeting mode to attack with ranged weapons.

Doors

Move into doors to open them. Use targeting mode to close them.

Interact with items on the ground

Use the Interact command to stand still and search, pickup items, open chests and ascend/descend stairs. If you have a touch screen enabled handset just tap on the player character to interact with something on the ground below you.

Targeting

Use the Targeting command to switch to Targeting mode. While in Targeting mode you can use the Movement commands to move a cursor around on the map.

Press the Targeting command multiple times to cycle between equipment or plain inspection mode. If you have a touch screen enabled handset tap and hold for half a second to cycle equipment.

Use the Cycle Target command to cycle between visible targets.

Use the Interact command to interact with selected target using the selected equipment (or no equipment to inpsect a monster/item or close a door). If you have a touch screen enabled handset just tap on a target to immediately Interact with it.

Use the Exit command to go back to movement mode again. If you have a touch screen enabled handset tap the bottom of the screen to go back to movement mode again.

Menu

Use Menu command to bring up the game menu (inventory, character info, new game, save/load etc). If you have a touch screen enabled handset simply tap the bottom of the screen to open the menu.

Use the Menu command again to cancel/go back from the current menu. If you have a touch screen enabled handset drag left to cancel/go back from the current menu.

Inventory

You can access the Inventory from the main menu or by using the Inventory command. Touch screen uses have to go via the main menu to access the inventory.

Character stats

Your character has four attributes; Attack, Defense, Magic and Speed. When displayed ingame the are shown as Attack/Defence/Magic/Speed.

• Attack determines chance of doing damage in combat and the amount of damage that can be done in melee combat. Attack can be increased by using weapons and other items found in the dungeon.

• Defense determines your chance of negating incoming damage.

• Magic determines your ability to use magic items and deal damage with spell. It also increases your chances of resisting magic attacks.

• Speed determines the speed by which you act, allowing you to attack and move more often than your opponents.

Besides the four attributes your character has Hit Points (Magic Points was removed in a recent version). When Hit Points reach 0 you die and have to start over.

Inventory and Equipment

The inventory shows all carried and equiped items. Available equipment slots are:

• Melee Weapon
• Missile Weapon and ammo
• Armour
• Shield
• Helmet
• Boots
• Ring
• Amulet
• Cloak
• Trinket (wand or similar)
• Spell book

Use your inventory to equip/remove/drop/examine items you are carrying. Some weapons require both hands to use, thus preventing the use of a shield.

Known handset issues

• On some handsets the key names for joypad and similar non numeric keys aren't shown when using Defined Keys and Show Commands
• 2009-09: On HTC Dash handsets the player is rendered at the bottom of the screen. Probably caused by the handset reporting an incorrect(?) screen height

Todo list and ideas

User experience

• Add more in-game help

Bugs

• It should be possible to disarm traps even if there is an item on the map cell where the trap is.

Character and character progression

• Sometimes give passive abilities on level up. The Warrior has a chance to knock-back enemies. The Ranger has a chance to temporarily pin enemies to the ground using arrows (effectively a stun). The Wizard has a chance to drain life from a killed monster.
• Achievements (kill n monsters, kill n monsters of a certain type, accumulate x gold etc). Give in-game benefits or add to final score.
• Add the option to name the player character

Death/Win

• Improve "game over" screen
• Possibly add an item (soulwell, soulgem or similar) that when dead will be consumed and return you to life on the surface with your equipment (and possible with a small loss of stats).

Gameplay

• Possibly add difficulty levels (Easy, Normal, Hard). Maybe prevent use of stairs up on Hard or something? No starting inventory? Separate highscore tables (or a single one with a score bonus depending on difficulty).

Inventory

• Switch to a grid system

Items

• Other lightsources (fires, torches)
• More items for the ranger. Concussive arrows (stuns opponent), Explosive arrows (knockback)
• Add level/stat restrictions to items
• Combine/transmute items (two weak potions = one strong, one healing potion and some herbs = stat gain potion etc)
• Destroy items

Interface

• Virtual dpad for touchscreen devices

Map

• Perhaps add several stairs up/down, possibly to different branches ("You see a staircase leading down to the sewers", "You see a staircase leading down to a dungeon")
• Sewers: Add junk that can be searched for items (can spawn monsters and/or cause disease)
• New map type: Catacombs. Undead monsters mostly. Coffins that can be opened for loot/monsters
• New map elements: Altar (sacrifice items to gain favors), Teleporter, Fountain (healing, antidote, mutation, poison)
• Not possible to disarm traps if an item is on the same position
• Doors only unlockable by special keys
• Sokoban style rooms that when completed opens a door to a treasure room

Merchant

• No suggestions at the moment

Monsters

• Add some kind of danger assessment to monsters (Harmless, Weak, Even, Dangerous, Deadly etc)
• Immobile monsters: Statues, Deadly plants
• More monsters!
• Monsters should avoid undiscovered traps (they already avoid discovered traps)
• Charmed/summoned monster AI need to be improved
• Monsters (esp. charmed ones) should follow up/down stairs
• Allow monsters to have more than one spell in their arsenal

Performance

• Screen flickers on some handsets due to too frequent redraws of too much of the screen (ex. Nokia N97Mini)

Quests

• Add mini quests

Social Networking and External systems

• Add Facebook support (post Dweller highscores to a users FB page, when finding an artifact weapon and so on
• Char dump to SMS/Mail/Webpage/Social Media Site
• Possible put the game on Handster.com, Mobango.com and Appoke

Spells

• Curse (decreases chance of attacking/casting spells or maybe preventing items from being removed)
• Acid (damages inventory and/or equipment)

Targeting

• Cycle between all available items (scrolls, books, wands)

SUGGESTIONS AND IDEAS THAT HAVE BEEN DISCARDED

• Place stairs further apart. Note: There is nothing wrong with having stairs close. The player does not need to be forced to explore the whole dungeon as it in many aspects already is a necessity to survive and gear up before going deeper.
• Investigate if a Rest command should be added (regain HP with the risk of monsters ambushing). Note: There is no real need for this anymore as you have the merchant on the first level to buy healing potions from. Even with the risk of being ambushed when resting it would make the game too easy.
