My third game built in JavaScript Canvas (HTML5). It's a top-down "bullet hell" shooter. The goal is to defeat all of the enemy fortresses, which are randomly generated and come in various difficulty levels. At later stages it is impossible to avoid enemy fire and you need to rely on having fast health regeneration and max health.

You can play it below, or open it in a new window by clicking here (can prevent some text highlighting issues). It requires a modern browser to play and generally runs the fastest in Chrome.
