Mój drugi skrypt - Arkanoid

[neq5]

Hej ;] Naklikałem drugi skrypt w pythonie w życiu. To gra arkanoid.

Aby uruchomić skrypt, należy wcześniej zainstalować moduł Pygame Zero (pip3 install pgzero) oraz zgrać obrazki do katalogu images (najlepiej zrobić "git clone https://github.com/neq5/arkanoid").

Poniżej skrypt. Sterowanie strzałkami lewo/prawo.
