InkTower: Idle Tower Defense

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. Compete at a desk of twenty in your league, climb the leagues 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.
