UPDATE

I am currently drawing new tiles to replace the ones from the Castle. The new tiles work well, but they're nothing too elaborate. I like the set with and without the Castle graphics, but they both look very different. If Radium will host them, I will put up some comparison shots once I have the new tiles ready, and we can see what people like better.

Also, I'll be looking for people to test the level very soon, before I upload it. I didn't know until just recently about the layer 5 vs layer 8 problem. I've got layers 5 and 8 going in opposite directions and at different speeds, and I've never run into the problem of a jittery background. I need to see what results other people have.
