'''
Spyce Invaders - slightly modified clone of Space Invaders classic game
implemented with pyxel (https://github.com/kitao/pyxel).

Shoot all the invaders before they reach you or destroy you!

Controls:
    ↑ and ↓ arrow keys to select options in menus,
    ENTER to choose option in menus,
    ← and → arrow keys to move the laser cannon left and right,
    SPACE to shoot the laser cannon,
    Q or P to pause the game.

Created by @skamieniarz (https://github.com/skamieniarz) in 2019.
