1Drag anywhere to slide the cannon. On a computer, the arrow keys or A and D work too. It fires on its own.
2Run your soldiers through blue gates and around red ones. Jars soak up soldiers until they are full, then burst out five times as many.
3Shoot the floating power-ups: rapid fire, a ruler wall, and an ink bomb.
4A red soldier that reaches your dashed line costs a heart. Empty the castle's health bar to win.
About it
A pen cannon at the bottom of a notebook page fires blue ink soldiers up toward a red castle. Sticky-note gates on the way multiply them: ×2, ×3, ×5, or a burst of forty at a time. Red notes halve them or wipe them out.
Red soldiers march down to meet you: fast runners, tough shields, splitters that break in two, and big erasers that take hundreds of hits. Every fifth level is a boss castle that shoots back, moves, or hides behind a shield.
Levels never run out, and there is an endless mode. Coins buy faster fire, bigger shots, extra hearts and new cannons: a fast pencil, a fat marker and a stapler that fires in bursts. Everything is saved on your device.
Slide the cannon under the right gates and a trickle of ink turns into a flood.
