My Little Pegasus: Kizuna DoPonyPachi developer Giest118 has released a significantly revised version of his Cave-inspired freeware bullet hell shoot-'em-up Trigonometry Wars 3 for Windows. More project details are available here.

Don't be fooled by the simplistic visuals -- the action here is well-designed throughout, and the complex bullet patterns will challenge you from the get-go. It also has gamepad support, and if the five included stages aren't difficult enough for your liking, a more challenging second loop awaits you after you beat the final boss.

(Bonus points for the unnecessarily vulgar how-to-play screen, too!)
