Hi Guys (and maybe girls )

I've been reading this board a while now and found a lot of really cool solutions for my problems...mostly without asking anything Thanks for this board!

I just created a small game which is kind of a quiz for video games. There is a bunch of different categories and questions.
Can you guys tell me if you have problems with this app? What do you like about the app? Are the questions too hard? Thanks a lot for any comments.
