About Tank Rush
Tank Rush is a top-down tank shooter with a shop between levels. You drive one tank through 29 procedurally generated levels and an endless arena, and a level ends only when every enemy tank, gun turret and spawner on it is destroyed. Kills, crates and barrels drop coins, and once the last enemy dies you keep driving to collect whatever is still lying around before you cash out. Dying ends the level but you keep the coins you picked up, so a failed attempt still pays for something.
Drive with WASD or the arrow keys, aim and fire with the mouse, change weapon with 1-6 or the scroll wheel, pause with Esc. It wants a keyboard and mouse; there are no touch controls. Coins buy ten upgrade steps each of armour, visibility, turret speed and movement speed, plus six weapons - minigun, shotgun, ricochet, cannon, homing rockets and a laser - with nine upgrades apiece. Enemies carry that same arsenal from level 2 onward: they path around walls to reach you, bounce ricochet shots off corners, and draw a warning line before a laser fires. Each level's difficulty is derived from the upgrades you could afford by then, so level 20 should feel about as tight as level 1. Start on medium and buy the shotgun first.

The prompt behind Tank Rush
Build a top-down browser tank shooter with a progression loop: drop into a map, destroy the enemy spawners, tanks, barrels and crates, WASD to move and mouse to aim, earn money to upgrade armour, speed, turret and weapons, enemies get stronger every level. Then a long play-test loop, driven entirely by what the game felt like to play: keep every level as tight as level 1 given the upgrades affordable by then, which became a balance model that derives enemy HP and damage from the player's expected power curve; make the economy grindy, with no free crates near spawn; give enemies the whole arsenal from level 2; flat, calm UI on one fixed 960x800 stage; single-shade fog of war where explored ground stays visible; a loot phase after the last kill; 30 levels across two pages with the last one an endless symmetrical arena. Late fixes came from watching the tanks misbehave: rockets that homed through walls, tanks that drove into a wall instead of around it, and stuck tanks that wiggled in place - answered with a breadth-first flow field, line-of-sight target selection, crowd separation and ricochet bank-shot aiming.
