pygame(python) Коллизия

Есть "player"(спрайт) и группа стен(other_group), тоже спрайты. При создании стены с НЕ одинаковыми координатами по x/y, не коректно отрабатывает метод sprite.spritecollide. конкретнее по горизонтали все окей, по вертикали player просто проваливается в стену. пытался переписать с другими методами, результат все тот же.

# class стены
class Tile(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__(other_group)
        self.image = wall_images
        self.rect = self.image.get_rect().move(x, y)
class Player(pygame.sprite.Sprite):
    def __init__(self, speed, x, y):
        super().__init__(player_group)
        self.speed = speed
        self.frames = []
        self.cur_frame = 0
        self.image = animation_down[0]
        self.rect = self.image.get_rect().move(x, y)
        
    def dorabotat_possibility_move(self, directory_of_movement):
        if directory_of_movement == 'right':
            tester = Player(self.speed, self.rect[0] + self.speed, self.rect[1])
        elif directory_of_movement == 'left':
            tester = Player(self.speed, self.rect[0] - self.speed, self.rect[1])
        elif directory_of_movement == 'up':
            tester = Player(self.speed, self.rect[1] - self.speed, self.rect[0])
        else:
            tester = Player(self.speed, self.rect[1] + self.speed, self.rect[0])

        if pygame.sprite.spritecollide(tester, other_group, dokill=False, collided=pygame.sprite.collide_rect_ratio(0.7)):
            print('collision')
            tester.kill()
            return False
