A downloadable game for Windows, macOS, and Linux

Abyss: Prison of Fear™ is an atmospheric puzzle adventure inspired by Myst and Riven but with a darker tone for a Halloween season release. This is meant to be a very small experience — just a prototype and practice project — not an expansive, full game.

If you enjoy it or have any trouble with it, please contact me: Drew on Twitter


I currently recommend mouse/keyboard (WASD) but xbox gamepad is technically supported, although it needs a lot of work to feel proper.


Note that this is my first time making a game with:

  • first person 3D perspective and interaction
  • semi-realistic reflection, refraction, and indirect lighting
  • mostly pre-made audio/visual assets I didn't create myself
  • original puzzle design and a Myst like adventure
  • dark, spooky theme for Halloween


  • Oct 31, v0.0.9.2 fixes, tweaks, polish... time to play!
  • Oct 30, v0.0.9.1 fixes, tweaks, polish
  • Oct 29, v0.0.9 Feels: ambient audio and finale
  • Oct 23, v0.0.8.1 fixes and tweaks
  • Oct 22, v0.0.8 Pathfinder: challenge upgrade
  • Oct 17, v0.0.7 Firestone: graphics overhaul
  • Oct 14, v0.0.6 Title Mode: smooth transitions
  • Oct 9, v0.0.5 Dark Mode: lights down low
  • Oct 7, v0.0.4 Footsteps: ground types
  • Oct 4, v0.0.3 Sounds: interaction sounds
  • Oct 3, v0.0.2 Puzzles: interactions begin

It's looking good so far! I had made you a video on Halloween night! ^_^ : 

thanks so much for booting it up! sad that you missed most of the game. you seemed to overlook ***PUZZLE SPOILERS*** that you can walk up the stone ramp and that you can push a button to operate the gates. and i'd love to improve it to avoid that: what do you think made it tough to realize that there was more to the game?

Nah, just me being a N00b.  ^_^


thanks so much for playing! left you comments and questions on your video
