1.Sprite sheets are allowed
2.Scaling and rotating inst something everyone agrees on, so use at your own risk
3.You *could *stitch multiple sprites together, but it does defeat the purpose of the limitation
I have an additional question: can I have a background tileset with 8x8 tiles or something bigger than 4x4? Even if the tileset includes some static/stationary world "objects" (like platforms etc...), instead of just background tiles?
