Really good stuff~. Found it from a ManlyBadassHero video.
Good attention to detail and character behavior. I'll try not to spoil but, the events of the game make sense.
I like the ending too. Wish I could talk about why but, I'm not gonna spoil it for anyone else looking to try it.
One thing though, maybe give a bit more room for error in puzzles for your future games. The "bleed out" one has a pretty tight margin.
