objective

Defend the ★ base and wipe out every enemy that spawns. Bricks are destructible · steel is not · bushes hide line of sight · water blocks tanks but bullets fly across. Five stages, three enemy AI flavours and a boss on the final stage. Lives reset to 3 at the start of each stage. Pick up S·shield · 2X·spread · RF·rapid-fire · +1·heal · F·base-fortify (steel walls for 16 s) — they drop from kills and also spawn periodically on the map.

// note — the canvas is paused automatically when the tab is hidden or the window loses focus, so you never lose progress to a stray tab switch.
