I love the main idea, the mechanic of leaving corpse to fulfil some purpose is really nice. The game could use a bit more polish, but the same is true for every other game, and is unavoidable in a 48-hour gamejam.
I have a feeling this game would be nice for speedrunners, there are lot of places to exploit. (In one place I got out of bounds without wanting to several times, and being on top out of bounds I could trigger the checkpoints.) And there is the nice mechanic of "flight by reincarnation" :D.
