waleedalqalaf is it fine if i add powerups instead of a shop feature? I actuallly am a complete beginner so cant make complex code :)
its your game, you can make whatever you want :P. Powerups are cool too. Making shops is not complex either. The simplest idea of a shop would be, you have a button, when you click on that button it just checks if your money is bigger than or equal to the price (lets say 10). then give the upgrade, and subtract 10 from money. Otherwise do nothing.
If balance >= 10:
balance -= 10

Also nice you added the feature! :P
