When I first played this when I was very young, I thought that it was a game that was actually made by Sega/Sonic Team, that it was a demo that they uploaded onto the internet because I thought it was that impressive. (I didn't pay attention to the disclaimer in the beginning. :P)

Obviously now I can see the cracks of a Flash game made with a very old version of the software, especially this one - but still, as a 2004 Flash game this is quite impressive! Probably cutting-edge for its time. So kudos to you, Dennis-Gid! And thanks for the good memories! :)

Good ol' Elementary School memories!! I would always play this all the time when i'm at the computer lab. Still a great and memorable Flash Sonic Game!

This Is One Of The Better Sonic Flash Games It's Very Well Made, Controls Are Nice, And It Has A Good Character Selection. Overall This May Always Be THE Best Sonic Flash Game.

I Like this Game!

good game, physics mess up sometimes, there's a bug in act 2 where you clip through the floor, and one in act 1 with the crab robots where they keep shooting forever and stop moving.

and one bug where you can get hit on a spike and get hit again in like a millisecond even if you collect any rings you still die, its a fun game tho.

the level design in act 2 is unfair in one point where you have to take a leap of faith and then you get bounced over directly into an area that will either have you
-fall on a spike
-fall onto an enemy
-get flung into another enemy
act has a significant difficulty spike to me.
