I've never ragequit and returned to a game more than this one and I've gotten all the Band-Aids in Original Meatboy and Beat Super Meat Boy
. . . fun unique mechanic but "dying" is far too punishing, seriously played it for hours and only made it to the bottom of the pirate section. No individual jump puzzle is too hard, but the punishment for screwing up being falling potentially multiple 'levels' down where you could screw up and fall again . . . you're never more than like 3 screw ups from falling all the way back into the cave and that's pretty bad. It needs checkpoints or sections where the floor is more complete to prevent complete restart . . .
I'd like to rate it highly for a unique/fun mechanic and decent art/sound, but . . . I can't without it being reasonably hard instead of perfectionistic.
