And this is not how you have to type when you ask something to other ppl :)
And guess what ? It's easier to type without putting a cap at each word ! (and polite ...)
So, you are looking for ideas ... ? It's the easiest part in game making ! If you are a rookie in C2 you should start with small projet, like clone of existing game. For example you could clone the flappy bird game without looking at the template.
You have to train a lot.
This is my point of view, you can wait for other advices !
