What game engine is this?

I'm not sure whether I should have posted this in Video Games or new media, so if this isn't the place for flash games, let me know.

I've played a couple games created with this game engine (the logo looks like a capital F made of multicolor pixels) like Level Up and the Robot Wants series. Every single one has been fantastic. I was just wondering if anyone could tell me what engine these games were made on so I could go to the website and look up more games

Edit: Oh, and this is a fantastic game. I suggest you play it.

It's flixel, which is a bunch of AS3 files. Not sure you can really refer to it as an engine (I'd call it a library, personally), but bluh.

Awesome! I figured it wasn't an engine per se, but I didn't know what else to call it
