I found some sprites on MFGG and it was so good that I want to create a game with them. If you want to know what I mean, http://mfgg.net/index.php?act=resdb¶m=02&c=1&id=33452.
The reason is that it is ONLY for Apple. I have a Samsung S6 Edge and I want to play to. So I want to create a fan-made game for PC AND Samsung in "Super Mario World" style.
