Hello, thanks for playing my little game and sorry my reply is so late.
I'm aware of those shortcomings, though to my defense the game was originally planed much smaller in scope since it is the first game I ever published.
But while making it I added one feature after another and now it's kind of a mess with a few problems as you pointed out.
So to answer your last point, I myself don't know where to go with it so I will make it look a little nicer and then move on to a new project.
