i ran your code and it looked like the white bars were jiggling until i went 2x on the iPad. if those are meant to be electric streams I think you should look at showing it some other way. You know how you can use the lightning effect in Maya? you could do something like that. render out some lightning strikes, make it match the rest of your artwork, and make an image sequence (i think UIImageView can do image sequences) it's also way too easy to hit the bytes, the spider is pretty wide. imo you should make the spider skinnier than the streams that the bytes are flying along or make the bytes skinnier. Or at least for the first few levels. or perhaps you have some penalty bonus that makes you fat and more likely to collide with the bytes also, you should rotate your images and shrink them (you can do that in preview) I haven't updated the 1x graphics yet because I'm still messing with them, that's why it's doing weird things You're not the first to suggest making it smaller but the thing is the 1x is a small as it can get, so I think I'll have to shrink the bytes (I think I'm going to wish I didn't use literals again ) The grey things the move on the background aren't really supposed to be anything, I was just trying to give a sense of movement.
