"a choice of weapon" is a simple 2D shooter where the player can choose between using a powerful sniper or a messy machine gun. They're both useful, but in very different situations. As so, the player uses the two mouse buttons to control which weapon to fire. I decided to follow the "Two Button Controls" theme. In addition, the game features synchronisation with the music so the difficulty of the game is based on the music. I submitted it exactly 9 hours after the theme announcement.
