If you want more, couldn't you just create blank foreground tiles with the passability info (so you can reuse them) and then use the more background tiles trick? Kinda like how the Keen 4 world map does.levellass wrote:As I said, there's no pressing need as long as you just want extra background tiles, but I'll see if I can do something.
Then you can just use foreground tiles only when you need special properties of them (like keen walking behind them).
