I should preface my comment by saying I'm usually not a big fan of platformers, probably because I usually suck at them. But I'm especially not a fan of frustrating platformers in jams, so this was already not going to be a game for me.
There's a lot to like, the graphics and audio are nice, and I like the detail of being bale to use your own corpse for a platform to jump on. But I just don't find much joy in repeatedly dying and starting over. The changing controls I think fall under being "so bad its good", but for me the overall loop falls kinda flat.
The game is well put together for an intentionally frustrating game, it's just not for me.
Good work!
