After a few days of developing this game then discontinuing it, I had the motivation to complete 0.1.0 and publishing it led me to a success - a YouTuber finally played my game. Some quotes that made me laugh were:

"Blurry Sonic, good."

"Wow, you're slow. Sonic, speed it up, my friend."

"We just decimated the bird population. Birds no longer exist."

"'-Hide and Seek!' Look, he actually said it."

"How do I hide? Hello? I need to hide please."

"'Found you!' I know, I noticed."

Although Green Hill is short, it still tells the backstory.

Although Tails' Doom is also short, it was still fun.

So was Knuckles' Doom.

P.S: Sorry about the Eggman.

I would like to thank everyone who played the game for early support - even though it had a rubbish physics engine.
