Descriptions, ready to paste
One line
An endless arcade game for iPhone where you defend the bottom of the screen with a rainbow cannon that only pops the colour you fire.
Short (50 words)
Colour-stealing orbs drift down the screen. You answer from the bottom with a rainbow cannon, firing laser waves that pop only what matches. Read fast and you stay ahead of it; guess, and the cannon overheats. Twelve kinds of orb, an uncapped streak, a daily sixty-second challenge, and no way to buy your way up the leaderboard.
Long (150 words)
Color Killer is an endless arcade game built natively for iPhone. Orbs fall; a rainbow cannon sits at the bottom; a wave only pops the colour that fired it. The depth comes from what that costs. Firing spends charge and landing the shot refunds most of it, so accurate play sustains about three kills a second and blind play barely one — answering a single orb with all seven colours empties the bar and overheats the cannon for six tenths of a second. The streak multiplier has no ceiling: doubling at two, quadrupling at four, ×8 at eight, then +2 every further two kills forever. What holds it in check is the miss rule — a wave that reaches the top without connecting breaks the streak outright. A hundred and twenty clean kills also charges the Rainbow: ten seconds in which every wave connects with any colour and the multiplier doubles. Twelve orb types change what a hit means, and the game refuses to draw the ones that need reading on levels moving too fast to read them. Every colour also carries a distinct shape, so it is fully playable without relying on hue.
