So I've been thinking of trying to make a 2D Sonic Fangame for a while now and recently I knew I wanted to do so. There's a problem though, I have no engine to make said game. I searched through the internet and forums to no avail. I would make my own but I have no experience and it would be a tall order just to try to make something on my own. I looked into to certain ones but some never fit my needs so if anyone can help that would be great.
