I need two screens. First screen is the title screen which shows the name of the app, the current difficulty level, and three options: Play, Difficulty, and Leaderboard. Leaderboard will only show up if the user has successfully logged in. If the user doesn't log in, the only two buttons will be displayed. (Leaderboard can be disabled or greyed out, too.)
The second screen is the play screen. You're free to go crazy here: the concept is the score, timer, and current degrees of rotation on the top. The bottom area is the playfield. Please see the attached graphics for more concepts.
The bottom area of the display can be moved, but the size will not change. It takes up most of the bottom of the screen. I can use images for the graphics in the game area, but I'd prefer not to: I want to keep with the design of the graphics you provide. If you deem the use of graphics and images in that area to be more appropriate, I'll consider them in the overall ending design if it's compelling enough.
Things I like in a game like this might be a wood-grained or metallic texture, perhaps an organic feel to it.
The game screen must be iPhone 4 compatible. I already have icons for the app, all I need are the game screens.
Screen graphics must be 640 x 960 in dimensions. Game play is only in portrait mode, which means the layout will never change, only the way you hold the phone.
