Considering it is your first game and you are only 11 there is not much more to ask for really! The game obviously has problems, but most of them are game design and level design I would say (or random stuff unity does for no reason and you kinda have to know how to get around for it to work properly). And this is pretty much a matter of time to learn how to do and maybe watch some documentaries on the subject. The fact you are putting your effort into something you enjoy and it is functioning is great! That is everyone's first step and you have done your really early on.
