In bullet hell mining game Astro Prospector the real enemy is sleep
I'm writing up Astro Prospector for a couple of reasons: firstly, it reminds me of two childhood favourites, Atari's Asteroids and the less-known Crystal Quest for the Macintosh. And secondly, there's something appealingly perverse about a bullet hell of all gametypes that is always simulating the player nodding off at the keyboard.
