I loved the intro movie you made, that was extremely cute. I was able to make my way to the end of the dungeon, I think it would have been more satisfying to have either a final battle or a puzzle to solve to unlock your friend maybe? The attack and damage all appears to be functional IE I could damage enemies and they could damage me, but maybe the projectiles were going too quickly as I couldn't see them most of the time. If you have time to look into the particle system for unity, the main character's attack would have been a really good place to use them for added visual impact.
