I Really like the style of the game, but got soft locked twice. one at the beginning of the game just before the second save point. if you go left you cant leave that area. the second soft lock was with the boss rust. i entered the room and it didn't trigger, or idk. but i was stuck in there could not get out. also the heart boss seems way to hard, but you can leave at the bottom, idk if it was intended. over all good job! :D
