Just to make it clear, I'm not mad or anything like that at the creator of this Fan-Game, I just wanted to show you that there's already a Fan-Game based on "Steamboat Willie", I don't need to be upset or worried about another Fan-Game that had the same idea as me because I know that my game is VERY different from this game, be it art direction, mechanics, story and etc..., so don't worry, the game is still active, and if you can, go check out this Fan-Game, it looks really good!!! I would even play it, but it's only available for Mac, and my PC is Windows, so it won't happen, not for now...

EDIT: I just saw that @Caleb_Hill (the creator of the Fan-Game in the image) posted a Windows demo of his game, and I played and beat that demo, I can firmly say that the game is amazing! Keep up the great work man! And as suspected, my game is VERY different from this game, so there will be no creative conflicts overall!
