Nice work! Excellent atmosphere, the art and music are great. I’m into the mechanics, though wanted a lot more, especially give the size of the world; once I got double jump, I felt like I was mostly exploring. I saw a cracked tile, and of course several blocked passages so hopefully there’s some good stuff in the works.
One minor annoyance, changing levels left you vulnerable so if a rolly bug was after you when exiting, you’d be locked in to taking the hit. I also really wanted some movement while absorbing, at the very least keeping momentum while jumping.
A small bug-but-actually-this-was-cool: in the room before the end, when you leave it puts you into the save room instead. I went above, then walked back because it felt like a boss was near, was pleasantly surprised to find myself in the save room.
