A good idea, but there are some balance and scaling issues. Maps 1, 2, and 3, are a nice, gradiated intro to the game. Then map 4 is WAY too difficult. I gave up after about six tries. Still, very original! 4/5.
Awesome idea! Fantastic use of space. Controls aren't always intuitive and when the play area gets small things are a little hard to see, but otherwise, great! Still, 5/5 game. Thanks for posting!
