Radius Raid
In Radius Raid you pilot a little ship around an overhead arena that is twice as big as your screen. The keyboard moves your ship while the mouse points the gun, so you can flee one way and shoot another. Enemies drift in from every edge, and each new level adds a fresh kind with its own habits.
Jack Rugile built Radius Raid for js13kGames in 2013, creating every shape and sound effect in code. It needs nothing more than a browser and a mouse.
How to play Radius Raid
Press PLAY. Your ship turns to face the pointer, and holding the left mouse button fires a stream of shots in that direction. Enemies never shoot. Damage comes only from bumping into them, and your health keeps slipping away for every moment one stays in contact.
Kills earn between 5 and 65 points depending on the enemy. They also fill the Progress bar at the top, and a full bar takes you to the next level. The first level asks for 17 kills, and every later level asks for 7 more. New arrivals include splitters that break into four pieces, ghostly stealth ships and spawners that keep releasing small chasers.
Once all thirteen enemy types are in play, levels keep coming with tougher foes. When your health runs out, a summary lists your score, level, kills, shots fired and time.

Tips
- Use short taps on the movement keys. The ship glides and slows gradually, which lets you slip past an enemy instead of stopping on it.
- Watch the small map for dots heading your way, and swing your aim toward them before they reach the screen.
- Destroy splitters at long range, so you have space to mop up the four pieces they break into.
- Target spawners as soon as they appear. They keep pumping out chasers until they are gone.
- Switch on autofire with F during long runs so you only have to think about steering and aiming.

Questions
Why did Radius Raid pause on its own?
The game pauses whenever its window loses focus, such as when you click somewhere else on the page. Press P or click the resume button to keep going.
Does Radius Raid keep my stats?
Yes. Your best score, best level, total kills and other numbers are stored in your browser and can be viewed from the STATS screen.
What power-ups are there?
Five timed ones: a health pack, slowed enemies, faster shots, triple shots and shots that pierce. Their timers show at the bottom of the screen.
