No, not Pixel--Flixel!
Semi-secretive dude, Adam Saltsman has been busy working on stuff other than artwork for Cave Story and another little game of ours. He's been building his version of a game maker. I'm far too lazy to explain what it's about so I just asked him to tell us, "[Flixel] is a free collection of actionscript files that help make it easier to make high performance flash games with a retro aesthetic without using the Adobe Flash IDE."
Thanks, Adam. Sounds fun! Now go make games at Flixel.org
