LÖVE

Because I want to post videos of my Löve programs on YouTube 'n' stuff.

QuickTime has a screen recorder built in but it records the entire screen. I just need to record my game's window. Any program that handles that?

Never use trully one but another way of capture is use the media player VLC. It have a capture mode. "open capture device","capture device > screen" but for the area you will need to input the values (no fancy mouse defining area I believe).

Also and with the tools you already had why not record all screen in quick time and later crop to desired area with iMovie.

There isn't a lot of FREE recorders for Mac but try this one

ffmpeg can record a section of the desktop, but you'll have to get your hands dirty with the command line. To find the position and size of a Window, you may be able to do this. I've only tried it in Linux, but I imagine it might work in OS X as well.

I tried that route before, but iMovie uses a fixed aspect ratio for its crop rectangle that I couldn't make to only cover the window I wanted to show.

You probably found a solution by now, but I use Quicktime (works very well)! So you don't need to buy anything.
You can record the whole screen, or just a portion of it, and there is an option to show mouse clicks
File > New Screen Recording… and it saves it as a .mov

You can use Soundflower to channel computer audio through a virtual microphone if you need to.

Hands down best software for this I've used is Screen Flow.

Sorry, didn't read the topic.

I use iShowU HD. The normal version doesn't cost all that much ($30) and works pretty well. The main downside is its bad performance. From what I've seen, I'd use ScreenFlow is I had the money to spend on it.
