Someone is drawing monsters in the margins. You drew a tower. InkTower is an idle tower defense sketched entirely in ballpoint pen in a school notebook. Every enemy, every explosion, every upgrade — hand-drawn doodles, redrawn live on every frame. DRAW TO FIGHT Sketch a wall with your finger to block the horde. Cross out a monster to hit it. Circle a spot to leave sticky ink. The tower shoots on its own — the page is where you help. BUILD YOUR ARSENAL Rockets, chain lightning, a circling saw blade, a harpoon, a flame ring, a spotlight, a death ray, a railgun — 8 weapons doodled around one stubborn tower, each with its own research branch. A SKILL TREE, NOT A LIST The lab is a tree with a live preview on every node. Overdrives, weapons bolted on from wave one, transformations that change how a weapon behaves. Research ticks in real time, even while the notebook is closed. THE MARGINS FIGHT BACK Blots, paper planes, a coffee stain that keeps growing, a UFO beaming down little blobs, a skull with a propeller that flies over your walls. Named page bosses: the Mother Blot, the Drummer Octopus, the Compass Spider, the Phoenix that gets back up once. TURN THE PAGE Survive deep enough and the notebook flips to a new page — tougher monsters, page events, and margin notes that tell the story of one very long school year. THE ALBUM AND PAGE GRADES Earn a sheet by playing, trace the dotted stencil with your finger, and the tower goes into battle wearing your drawing: hull, barrel, saw blades, rockets, 17 parts in all. The teacher stamps it ACCEPTED. Looks only, never a point of damage. The teacher also marks every page: PASSED, B, A, A+. Each mark pays gems and adds +0.5% damage and health for good, and every one of them goes on your REPORT CARD. MONTHLY LEADERBOARD Sign your notebook, and every run that reaches wave 15 goes on the board by itself. One table for the whole season: climb the top of all players and win gems. NO NONSENSE Ads are optional and never forced. No pay-to-win: gems buy research time, never damage. Coins and ink are never for sale.
