Prisma Defender

The sky is falling in colour. Every meteor arrives tinted, and your cannon fires whatever light you load into it. Dial in red, green and blue, match the shade exactly, and one shot is enough. Miss the mix and the shot is spent for nothing. HOW IT PLAYS Three sliders feed one barrel. A meteor the colour of deep violet needs red and blue in the right measure; a pale one needs all three. Set the mix, aim, fire. A perfect match destroys the meteor and pays half the light back into your tanks. A near miss strips one channel and leaves the rest falling. Light is finite. Every shot costs from the red, green and blue tanks, and the tanks only refill from clean kills. Waste shots and you run dry with the sky still full. The tension is not your reflexes, it is your accounting. THE PRISM SURGE Clean play overflows your tanks, and the overflow charges the Prism Surge. Fire it and the cannon runs on every wavelength at once for a few seconds: no dialling, nothing rejected, everything you touch dies. Tap it again to bank what is left and save those seconds for a wave that needs them. Let the Surge sit full and the overflow keeps going somewhere better. THE CARD PICK Overflow past a full Surge earns a pick. Three cards rise, turn face up so you see what is on offer, turn back down, and shuffle. Choose one and keep it: - PAUSE freezes the sky for five seconds - SLOW drops every meteor to a third speed - REWIND sends them back up the way they came Bank enough overflow and the jokers disappear from the deal, until every card on the table is worth having. Hold up to nine and play them when a wave turns. GATES Every five waves the sky stops and you spend what you scored. Widen a colour tank, reinforce the dome, or deepen the Surge. Trade light between colours when one channel runs dry and another is brimming. Prices climb as you buy, so a run is a series of choices about what you can afford to go without. THE DAILY CHALLENGE One run a day, and the same meteors in the same order for everyone playing that day. No retries. Your score is whatever you managed on the sky everyone else got. ALSO IN THE BOX - 12 achievements, from a single clean kill to eighteen meteors inside one Surge - 9 skins that change the sky, the planet and the stars, including seasonal ones - A local score board that remembers your best runs - Built for portrait, one hand, any length of sitting NO NONSENSE No ads. No accounts. No timers asking you to come back tomorrow. Nothing to buy. The whole game plays offline, on a plane, in a tunnel, with the wi-fi off. Prisma Defender is a game about reading a colour correctly under pressure, and about what it costs you when you read it wrong.
