A simple and fun web-based JS version of a tower defense game.

A web-based tower defense game built on JavaScript. Although the game interface is composed only of points, lines, and surfaces, it includes all the elements of a traditional tower defense game, making it seem simpler and more straightforward. Since it's built with JS, for smooth operation, please use IE9 or Chrome browser. The game's animation effects are beautiful, and it comes with three modes: Arcade (default map, less money at the start), Challenge (challenge mode, unlock ten maps in sequence), Perfection (perfect masochism mode, limited money, use until it's gone).
