Easily one of the best ROM hacks out there. The levels and custom bosses are a blast.
Tip for those having trouble: Bosses may look really hard, cheap, and impossible when you first encounter them. Take a breath and learn their pattern. Every boss has one. You will not have much of an issue with them after that.
I think my only complaint is that you could not save with every level completion, especially in world 8. It was extremely frustrating to be working on learning the Archdemon boss, getting a game over, and having to go through everything before it just to try again.
