Hi, my name is Dennis I from Ukraine, really like your program,
RUBE, but before you buy it you would like to ask what are people already know this, or you can use your program and xcode, create a game as a hill climb racing? As part of it will be implemented using the RUBE? Does level amplification (upgraite), and buttons will be created in the movement RUBE? And if you can add more extra buttons like a game earn to die, is it possible to level through RUBE add, click TURBO (acceleration), and the control buttons Rotation? Give please reply. And if possible examples of such games in appstore.

PS: Game is only for ios

Here are a couple of games similar to Hill Climb racing that use RUBE:

For the first one at least, the level was made from a single long chain shape. You can see a screenshot of one level in the editor here, along with some more info about it: http://www.box2d.org/forum/viewtopic.php?f=6&t=9314
I don't know about the second one.

As you can see in that forum post, RUBE was also used to make UI elements in the menu screens. You may find this YouTube video helpful about that: Creating menus with RUBE (Cocos2d)
