About this game
Players use the arrow keys or WASD to move and aim, Shift switches between spread/focused firing modes, Space consumes stored energy to fire the Star-Piercing Cannon, V activates a brief shield, and the main gun automatically fires to the right. During levels the background continuously scrolls left, passing through five star regions in sequence and looping; enemies appear in three formations with route warnings, and destroying a leader can briefly disrupt its squad members. The boss's upper and lower weapon groups can be destroyed separately; once destroyed, the corresponding attacks stop and the hull's attacks weaken. The field also includes energy canisters that can be detonated to clear enemy bullets, floating debris that can block bullets, and transport ships that drop supplies. After defeating the entire boss, choose one of three evolutions; there are also combo frenzy and dual-boss battles. Made with native HTML, CSS, JavaScript, Canvas 2D and Web Audio; play online or download and double-click index.html to play.
