I agree that the replayability isn't quite there, but I have some ideas to spice it up in future updates. Let's see if I can do anything about it. The ending is the same in Masochism mode, it's mostly the just for challenge. There are a couple of unique events in it though. And yeah, a happy(er) ending is planned. Not 100% sure about its details but it would probably be one of the bigger updates if it ever materializes. Glad you like the game!
