Pretty cool! Mechanics wise, it's pretty much Minecraft parkour mechanics except with better bouncing and worse ladders. Everything controls pretty consistent, except the poles/ropes/shafts that my character always lets go at random no matter how hard I'm pressing the crouch key. It does have that Getting Over It game design of losing all your progress in a single jump, so it's in no way accessible and that's a shame because the environment is really pretty and the music is good too before you've listened to all 2-5 tracks.

The horror aspect... It's kinda cool that it's there, but it doesn't really work for me 100%. Like, it's REALLY unlikely that you're going to get enough vertigo playing the game normally to make the creepy things have a decent chance of spawning. It's kinda scary when you intentionally look for it the first time, but it's very simple so it gets old after two or three times. Which I'm thankful for, I think keeping it as scary atmosphere with a shadow guy once in a while (which seems to be different for every player or playthrough!) is a really good way to go at it. But it's kinda doomed to not land right - be too aggressive and the horror distracts you from the already nightmarish jumps, be too mild and... well, the game as it is currently.
