Hello there,

When you say tiles, you mean only tiles for background and foreground (which means that player or other characters must have 8x8) or may I break a bigger sprite apart into 8x8 sprites and glue them in code, like GameBoy games used to do?

Cheers!

To clarify, yes, tiles mean for background and foreground. Basically, if you have a tileset for say walls, you may use it if it is bigger than 8x8 if the tiles themselves are 8x8. As for objects, you may use meta-sprites which are smaller sprites built up into a big sprite.
