I found this game to be a lot of fun. It's mostly because this is a game where you can really create whatever you want. Granted, there's still only a certain way to beat every level, but it's still great finding out! I liked all the sound effects. It's a great idea to have the princess be the villian. It was kind of strange when it seemed like you were trying to help her with this.
I know I got past some levels that I did not get medals for. Whatever, this is a well designed game. It was a nice inversion for the enemies. It's kind of like a smaller version of a defense game. I appreciate the creativity.
