Hi! I’m here waving at you this weekend because we’re hoping to continue to move Newgrounds away from ads. If you have $3 per month or $25 per year to spare, please consider becoming a Supporter today!
Flixel is an open source game-making library that is completely free for personal or commercial use. Written entirely in ActionScript 3 by Adam “Atomic” Saltsman, and designed to be used with free development tools. Flixel has since become part of HaxeFlixel, which is preferable for future development projects.
