This game gets chaotic pretty fast but it's fun :D
Though I did find a bug with the grape powerup: Shooting the grapes didn't seem to work properly most of the time. It was almost impossible to shoot them below Frank making it annoying to use and pretty useless.
The powerups were explained very well, however when I first played the game I just immediately went to quick play and didn't notice there was an option to see an explanation of the items. This made the first round a little confusing for me. Maybe it should show up when you press play for the first time.
Also I like the art a lot :)
