Far more difficult than I remember the SNES version being. Also, insanely weird and backward choice to have co-op be locked behind finishing the game first. Bad call.

Overall a fun and challenging game, although sometimes the challenge ramps up a bit TOO much. Would recommend with a friend, but you know, you gotta beat it alone first, which is dumb and sucks.

EDIT: They have added a cheat code to unlock co-op without having to beat the game alone. Good on them!
