Pokey: I'm glad you like it. I know about the fullscreening bug, and I was actually planning to remove that option, as it's useless on Maemo anyway. The right-click ability is currently just a quick hack to see if it works. (I've never actually even seen SDL code before, so this seemed the simplest way) As I said, changing resources (e.g. tilesets) is trivial, so feel free to give me a shout if you finish up a new set.
Right on - me too, actually, at least, to a higher degree.

Ed: the UI fits on the screen because I MADE it fit. It was all hardcoded. As for your idea, it would work, I think, but I'm not feeling like it right now. Maybe for the future.

Pokey: I'll ask for the money once I have the last few things worked out, but thanks. I'll PM you with my details now, however. I will probably spend a bit more time on this in the future, at least to maintain it, so I may change things like Ed's right-click idea later.

Cheers,
