555 before me!
This was a good game, but it could use work in some areas. The music was fantastic, especially the "Sonic Boom" stuff which simply never gets old. It also seemed to be pretty authentic to the Sonic games. I do wish that there could have been more control over your character. The menu is a bit difficult to understand, but still good. The obstacles seemed to be just like stuff you would encounter in "Sonic The Hedgehog" games.
The sprite work is well detailed, particularly with how the backgrounds are all unique. It can get confusing when using the arrow keys to control the cannon. When I saw the title, I seriously didn't think it was going to be taken literally! Well, I guess it depends on how you define "literally" in that sense. I also like how everything is presented in a fairly clearcut manner.
