Nice one! We also had an idea about using your corpses at first, and also for climbing or putting on the buttons. Cool idea that some buttons are only interactable by dead! Some of the levels were tricky, and for some reason I struggled to chain the jumps perfectly. Since it's possible to move the dead from below, maybe there should've been an ability to push them from sides? That probably would make some levels easier, but could be used for some other puzzles.
