This is something I've been trying to pull off since September. I tried my hardest and I also learned from past mistakes. I learned how to code on Tynker. I don't use it anymore. But I've made like 80 something projects. Please enjoy for I only have 3 out of the 7 zones. This is only a demo so please enjoy. Warning: DO NOT get the shield, it will randomly put itself out of existence for reasons I don't even know. Therefore, it will not be useful.
Thanks to @tomicool for the sprites, scripts, and level design. For the sprite sheets, my credit goes to Xinos for the Sonic sprites, and Cartoons Animate 22(I think thats the name)& SonicFan32 for the badnicks. Thank you so much for playing full game coming soon.
