W00t! Best game ever! Better than... uh, Sonic 1!
And Sonic2, and 3, and &Knux! Best flash game ever! And I have some suggestions for a sequel:
-Put in a Special Attack, like this: Badnik Call, where you call a bunch of badniks to attack the enemy!
-Put in Metal Sonic! He's my favorite, and a very important member of the Sonic Universe!
-Put in at least a few more stages! That Laser stage was creative, and cool! Put some more gimmicks in them, too! Spring Yard was awesome! The rooftop gimmick was excellent!
-Here's a good idea for a stage: Icecap, gimmick: If you fly over the snowboard at the top, you'll snowboard down to the other side of the screen, hurting the enemy if they're in the path, or escaping from them!
Hope you liked my ideas!
