If it's for practising then just make something that is interesting or useful to yourself.
Why not take a look at a game that you like and just build a similar game, perhaps adding a few features you wish you had.
Not every app or game has to be a completely new idea. There are probably a million versions of everything out there, make your version and make it better than everyone else's!
Please don't take offense as I haven't actually played it but that looks remarkably similar to flappy birds.
Not saying I could do better I was wondering if it's a reskin or ground up build?
I'll download it later regardless well done.
Good to hear. Sorry for being mistrustful just looked similar obviously having not played it I couldn't be sure.
I'll get on it tomorrow.
Going to release on iOS as well?
