It took nearly 5 years and most of my sanity, but the game is finally done. Check out the demo and buy the full game if you enjoy it!

  • Non-linear story - four possible endings
  • Oculus Rift support
  • Time trial mode
  • Built-in level editor with Steam Workshop support
  • Original soundtrack (available here)
  • Xbox 360 Controller support

Thank you so much to everyone for supporting me on this crazy journey! Hope you enjoy the final result.

You have got the in-game keyboard controls done very well.
Good job.

I presume it was an important thing to get right or the game would not have been an enjoyable experience to play.

I have to say this is one of the coolest games I've ever played. I was so impressed with your game and with how beautiful and smooth everything is. My playthrough with be up tomorrow and I also shared it with Zalzar who will most likely give it a go as well since he loves these types of games. Seriously, nice creation!

Hey, just wanna know I'm doing a game play of it, and I'm loving this game so far. I do have a suggestion-- maybe have the secrets include some sort of collectible or achievement, or something of that nature. At the end, if you've collected enough of whatever, you get an extra cut scene and extra game play? Just something I'd like personally, though.
