Radius Raid is Jack Rugile's entry to js13kGames 2013, a contest where a whole game has to fit in 13 kilobytes. You fly a small ship around a wide, scrolling arena and shoot everything that comes at you. Each level asks for a set number of kills and adds a new enemy type to the mix, up to thirteen, so the screen gets busier the longer you last.
Powerups drop from destroyed enemies and change how you play for a few seconds: faster fire, a three-way shot, shots that pierce, slowed enemies, extra health. Your best score and lifetime stats are kept in your browser. It needs a keyboard and a mouse, so it is a desktop game.

Tips for Radius Raid
Turn autofire on (F) as soon as you start, so you only have to think about moving and aiming.
Keep moving in wide circles rather than backing into an edge; enemies arrive from every side.
Grab powerups straight away. They do not stay on the ground for long.
