Nice level and music progression. The leitmotif was great, and the instrumentation kept evolving. I think this is my favorite music of the entire jam so far :)
I don't quite know if collecting more of the hourglasses would later give you more time to escape, but I assume that'd be the case. Not sure if all of them are actually collectible (I couldn't grab the one to the bottom left of the "GOTTEM" pit, it was too high up, and I didn't see any box or so to jump up)
Nice sprites, loved the different area designs :) There's a minor bug in the char animation though: when walking right, there's some pixel from another part of the spritesheet bleeding in.
Cool submission, well done!
