Prism Dash

Something is loose in the gallery, and the paintings have gone dark. You cut. Draw a line out into the dark, get back to solid ground, and whatever you fenced off is yours - the cover falls away and the painting underneath shows through. Fence off enough of it and the stage is cleared. The rule that makes it a game is where the fill goes. It does not fill where you drew; it fills wherever the monsters cannot reach. So the question is never "how much can I cut" but "which side are they on", and a single careless line hands the whole stage back to them. While you are drawing, the line is you. Touch it and you are gone. 48 PAINTINGS, AND THEY ARE THE REAL ONES "Mona Lisa", "The Starry Night", "The Great Wave off Kanagawa", "The Night Watch", "The Scream". Forty-eight in all, photographed from public-domain originals on Wikimedia Commons, each one a stage. Clear it and you get to look at it. SIX THINGS THAT WANT THE GALLERY BACK A dragon that lunges. A reaper. A sphinx that wakes when you start cutting. An armoured knight, a kraken, and a vampire that teleports with a half-second warning. They take turns, they bring their own minions, and everything gets faster every loop. ONE THUMB, PORTRAIT, ANYWHERE ON THE GLASS Press anywhere on the lower half and a direction pad appears under your thumb. There is no fixed control to reach for and no second hand needed. WATCH AN AD, KEEP WHAT YOU HAVE Lose your last life and a rewarded video carries you on in the same run: same score, same ground already claimed (up to 3 times per game). Between stages, if the bonus wheel lands on something you would rather not keep, a rewarded video lets you re-roll (up to 3 times per stage). Nothing else in the game is behind an ad, and there are no banners or interstitials. - Portrait mode, one-thumb control - No account, no sign-up, no in-app purchases - The game saves nothing to your device and uploads nothing
