PyInvaders Continued

Το tutorial του παρόντος τεύχους "φτιάξτε ένα arcade game με python" μου άνοιξε την όρεξη και είπα να το εμπλουτίσω κάπως.

Έβαλα 4 επίπεδα όπου αυξάνονται οι σειρές με τους εξωγήινους και η ταχυτητα του παιχνιδιού. (Προκαλώ οποιον θέλει να το τερματίσει εγώ δεν το κατάφερα ακόμα :) )

Επίσης υπάρχουν διάφοροι ήχοι, μουσική και εφέ όταν σκοτώνεται ένας εχθρός.

Τέλος κρατιέται to score κάτω δεξιά και το highcsore σε ξεχωριστό αρχείο. Παραθέτω τον κώδικα παρακάτω.

(Για να τρέξει χρειάζονται τα αρχεία του ήχου οι εικόνες και ένα απλό αρχείο text που θα κρατάει το high score τα οποία τα στέλνω σε όποιον ενδιαφέρεται).
