Sonic Ultra (SonicUltra)

This is my very first coding project, I made this just for fun. Since I'm a Sonic fan, I decided to make a Sonic game. 

Right now, the game has:

1 zone

1 act

1 boss

But when the game is done, it will have:

5 zones

10 acts in all

Bosses in each one

4 playable characters: Sonic, Tails, Knuckles, and another one that I will not tell.
