I found the controls a bit too skittish for the meatboy-esque difficulty and level design, and WASD+Spacebar probably isn't my platformer control style of choice. The level design was a bit mean sometimes too with seemingly-hidden wall jump passages that only led to death but I guess that's just the nature of an Indy inspired trap lair heh.
That's all nitpicking though, the game is super polished for a jam entry - all the art and sound were really nice, well done :)
