Extremely satisfying little puzzle game. It took me a while to understand how the velocity inversion worked and to get the timing of it, but once I got it I was platforming like a pro. The numbered doorway puzzle was particularly challenging and engaging. This game has the same vibe to me as Cats Are Liquid. Loved the minimalist art style. The red wall was more of an annoyance than anything and seems a bit buggy: I think when you go back through a checkpoint the red wall's current position is saved, so if you hit a checkpoint a second time the red wall will actually be closer to you than it was before, giving you very little time to work through stuff. I also almost ended up getting behind it, I'm convinced that if I really wanted to I could glitch behind it. It also wasn't super clear when i reached the end. Everything went white then I did a teleport jump and it all went black again. But yeah, other than those minor things, I really enjoyed this game!
