• A simple end goal, kill the Goblin king!
• Random dungeons (with optional persistence)
• Monsters with simple AI
• Items, item enchants and named artifact items
• Inventory and equipment
• Spells and ranged weapons
• FOV
• Save/Load
• ASCII/Graphics support

Dweller is designed to run on any MIDP2 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.

Doors

Move into doors to open 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 ot do a plain inpsect). 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.

Known bugs

• On some handsets the key names for joypad and similar non numeric keys aren't shown when using Defined Keys and Show Commands
• On HTC Dash handsets the player is rendered at the bottom of the screen. Probably caused by the handset reporting an incorrect(?) screen height
• On Nokia N73 handsets the double tile graphics doesn't show the correct graphics for out of sight tiles. The graphics come out as a black and white checkboard pattern instead of the intended black and transparent checkboard pattern

Todo list

Handset support

• Try to get the game running on Google Android

User experience

• Add more in-game help
• Make Dweller translatable

Inventory

• Add an option to Use Many (for instance use 3 Mushrooms of healing in one go, without having to go in to the menu between each use)

Map

• Place stairs further apart
• 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)
• Minimap
• Evaluate Fog of War monster "ghosts" - remove monsters and keep only items?

Monsters

• Add some kind of danger assessment to monsters (Harmless, Weak, Even, Dangerous, Deadly etc)
• Named monsters (mini bosses)
• Immobile monsters: Statues, Deadly plants
• Show monster description at first encounter of a new monster
• More monsters!
• Monsters should avoid undiscovered traps (they already avoid discovered traps)

Items

• Other lightsources (fires, torches)

Spells

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

Death/Win

• Improve "game over" screen

Gameplay

• Investigate if a Rest command should be added (regain HP with the risk of monsters ambushing)
