Pygame freezes after certain time

[GJG]

For some reason it freezes on Windows, I'll check on linux later, but it worked once I used a while loop instead of iterator and added event check. It's a simple letter puzzle game for assembling words, kind of like 2D rubik's cube.

count = 0
while count < 100:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    if count % 2 == 0:
        anim_move_right(randint(0, ltr_range - 1))
    else:
        anim_move_up(randint(0, ltr_range - 1))
    count += 1

pygame.quit()

Thanks for checking!
