Great concept, but the bugs (final battle not working properly), the lack of explanation in game, and the amount of grinding made it hard to enjoy. I still had fun, but this could definitely use some more work. It's a great idea and a great start, though. I never did get to see the 3 enemies together becoming strong, which is a shame cause that sounded cool. I liked the music but got annoyed when it kept restarting. Maybe use an autoload next time?
