Pixels fall. You catch them. They stick.
Guide a growing mass of pixels through an endless rain. Every pixel that touches it becomes part of it — and the bigger it gets, the further the camera pulls back, until your tower is a speck in a field you started as a single row.
The mass is heavy. It does not snap to your cursor; it leans, drifts and overshoots. Learning to lead it instead of chasing it is the whole game.
Miss too many and it ends. Catch the fancy ones — plus, square, line — and you buy back a mistake.
Spend what you collect on permanent upgrades: a faster mass, a magnetic pull, richer pixels, a longer life. Every purchase costs score you could have banked.
