EDIT 3/12/10: Right Click menu fixed, you can't skip levels anymore.

EDIT 2/6/10: Muzak fixed again because if you died, the music would just continue to loop, overlapping the entire thing, so say goodbye to that feature. Also, SOME rings added to Emerald Grove act 2.

EDIT 1/9/10: muzak fixed, now the music just loops from one point instead of the whole song.
SPINDASH also added, just press space with the direction you want to dash.
Rings also added, they give you health.

Acid fields act 1 still needs acid, and so does Act 2.

There is also a special zone.

this is my best game ever, don't judge it by its amateur animation.
I have taken all of your suggestions and making it better, except for the animation. The animation stays.
You people are HARSH when it comes to a sonic-related game.
EDIT: this is how it's going so far. the music is supposed to be in the right speaker and the sound effects play in the left speaker.
SEEEEGAAAA sound added. No matter what, I couldn't fix it so it won't say SEEEEGAAAA whenever you die. Also, good-bye Tails! we'll miss you!
I got rid of Tails because then I would have to keep going back and forth with the scripting, making sure Sonic and Tails have the same scripting, and it just got annoying.
So no more Tails.
