I really like cards from qop 1 and 2, much more then the zup ones, so I don't understand why qop 3 and 4 have no cards.. since the games were published some time ago I guess there's no hope that cards badges and background will be added.. am I right?

Something I've noticed in all three 'qop' games..which suggests it's a flaw in the engine...is that cube behaviour becomes very unpredictable during moments of heavy CPU usage. The most common one is that the cube will pass straight THROUGH a block which was supposed to stop it....

anyway to disable fullscreen and run it in a smaller window?

Hey, do you have an email address for business enquiries? thanks
