What it's like to play

Radius Raid puts an 800×600 viewport over a 1,600×1,200 arena. You move with WASD or the arrow keys, but the mouse sets the hero's facing; hold the left button to fire. The hero accelerates at 0.5 px per frame to a 6 px-per-frame cap, so direction changes carry momentum.

The default weapon fires every 5 frames — about 12 shots a second at 60 fps — and each bullet does 1 damage at 10 px per frame. F switches autofire on. There is no keyboard aim: the cursor is the gun.

There are 13 enemy types and five pickups: health, slow enemies, fast shot, triple shot and pierce shot. Level 1 ends at 17 kills; the target rises by 7 per level to 101 at level 13. The arena is twice the viewport in each direction, and the camera eases after the hero.

Score, level, rounds, kills, bullets, powerups and time are stored under one localStorage key. There is no meta-progression.

It suits players who want a pure twin-stick score chase.

13 enemy types and 5 powerups; kill targets run 17 to 101 across 13 levels.

The author's README recommends Chrome; the game is tuned for 60 fps.

Verdict: A pure twin-stick score chase: mouse aim, 13 enemy types and a kill target that climbs from 17 to 101.
