I looked on google for some articles on intuitive game UI design practices, but honestly I didn't get many results. Probably wrong combination of keywords. As much as I like my game's UI, I know it could be better. Anyone have any links? I'd post screens, but I'm on an iPad.

I don't know of any articles, but one simple suggestion I have is to test your designs. Give your game to somebody and see how the respond to the UI. If they don't understand something, figure out how to fix it.

If you are able to identify certain areas with your design that you are having problems with, I suggest posting screenshots to ux.stackexchange.com and asking specific questions.

Hello. See if this helps:

You can spend a lot of time here. But then afterwards you'll feel like you've never really done anything good.
