I’m not a big precision platformer guy, but I made it to the top anyway, woohoo! Pretty neat concept, and I quite like the low res pixel art style.
The spike hitboxes definitely feel a bit off. It was noticeable that sometimes when you’re falling down right besides a wall, with a spike on the bottom, that spike ends up killing you, which just feels wrong.
I also didn’t really understand the… vignette mechanic? Dying of cold maybe? It felt really inconsistent, and idk why going to the next room, which looks equally cold, would help anything? I’m not sure if it was bugged or if I just didn’t get it.
Aside from that and some little level design nitpicks (i.e. falling into a new room and immediately dying) this is quite well-crafted, the core mechanics feel good. Nice work!
