This is a good game, but I wish that it was more responsive, when I want to turn around or simple start walking again there's always a second where Sonic isn't doing anything, and then starts to go. This also applies to ducking, but it happened far less. Also, you can walk off the stage after completing it, which makes you die but also complete the level at the same time. You can also see the background under the ground. Other than those complaints, this game is pretty good and impressive for Scratch.
