Strange colours
 

Whenever I make my own lvl and export it, the rabits and enemies, even items, have ugly colours. How do I fix it? Is it because of the background?
Please, I need help! I wanna make my own levels!

It's the tileset you're using. Did you make it yourself? I don't know the details, but it has to do with the palette used in the tileset... You should be able to find details about it by searching the forums, but the easiest way is to simply use a different tileset.
