Cataclysm of Chaos
Cataclysm of Chaos, by Jason Roberts
Currently in Late Alpha, and is close to reaching Early Beta status.
The game is quite functional, offering quite a few hours of enjoyable gameplay already, and is fairly stable. Can play a myriad of different playstyles, including being a pure pacifist. It is an infinite "dungeon" sandbox where the player works towards their own goals and chooses which endings they wish to pursue.
Things that are missing are mostly endgame related stuff (ie Artifacts, Bosses, or Endings), interface improvements, tutorial/help system improvements, as well as testing to ensure that the code supports sound effects and tiled graphics, which is why the game is still considered Alpha, rather than Beta. I try to do weekly releases, and participate in Sharing Saturday on RoguelikeDev subreddit, so if I forget to upload here, then you can visit ShSa and grab the latest build there.
Current Latest build is Alpha V16 (as of Sept 15, 2018), and a binary (.exe) can be acquired from this link (windows only at the moment) = http://www.mediafire.com/file/qm8cob5cn9cxyce/BinaryV16.rar/file
