I liked the ability to pick up more circles and having the camera scroll out as my mob got bigger and bigger. Despite reading the directions, I still didnt realize I needed to press Start to have the enemies start coming until I was up to like... difficulty 17. Guess I was too focused on collecting guys. The music is a little repetitive but entertaining. It would be fun to see a version of this where you need to defend from enemies coming in while you pick up more guys, that would keep the suspense going as you have to try to prioritize getting stronger vs taking out enemies. Overall, this was a great use of theme!
