It was great!
There are several bugs:
When you leave the building in Joyless ending after killing Hart and his subordinate, Beltboy just stands on the entrance to the cliff instead of the scene being played. The game didn't freeze, Beltboy just wasn't moving because I heard him burping while I was waiting for anything to happen.
There is also an oversight where you can get +130 AGI (and other minor stat buffs) but I'm not telling you how because it's beneficial
There is also Fish Mask Beltboy mentioned in the files. Is it something scrapped or have I just missed it?
