Sharkanoid

Lunchtime entertainment based as loosely as possible on the classic 80s arcade game Arkanoid.
Arkanoid was a posh version of Breakout, and involved moving a bat around to bounce a ball against some blocks.
Arkanoid didn't involve our class headcase chasing us around school trying to whack us around our shorts-trousered legs with a large ruler. This was known, unlike the game Arkanoid, which this doesn't resemble at all, as "crisping".
You were briefly immune from crisping when you stood on a desk. Arkanoid had no such safety zone. However, to maintain this safety, you had to jump from desk to desk, like in Donkey Kong. Not Arkanoid.
