So far one of the best entries of the jam! The gameplay is engaging and clever, the graphics and the atmosphere are really cool, and I'm intrigued with the story. My only complaints are the position of the characters' names in the dialogue box (I had some problems recognizing who's talking, but it's a minor issue) and the bonemerang animation's speed (a bit too slow). Maybe you could give a specific color for each character who's speaking?
Really really reeeeeally good!
A side note: I'm sure you're completing this game (Because you HAVE TO complete this game XD) so I think that maybe you could introduce the many stages one at a time, with a slower pace without bringing the different skills all at once? It's just an advice, feel free to ignore it.
