I think this game is pretty good and mostly just needs polish in some areas. The animations are cool, but you can spam click to cancel them (not too big of a deal). While I find the combat satisfying, I do think it isn't that challenging, maybe having the blue spiders be much quicker could help. I also think that after the enemies die you can disable their collision, same thing for the destructible walls, making them lose collision instead of having to wait for the rubble to despawn. I think a sensitivity option would be great. Also, the game is a bit dark sometimes so maybe making the light ability a bit more intense could help.
Other than that, I really liked the level design, it was really fun exploring the maze-like levels and getting the new abilities to unlock even more places to explore. The memory puzzles in the last level were fun.
