If you guessed "Glow" you'd probably be right.

It's out for Mac OS X and Windows. The Windows one has a boss installer (thanks, SHilbert!) and the OS X one is well tested (thanks, Foobar of Integers!)

Here is the project page.

If everything goes well, I'll Showcase and IOTD it soon, then start farming out. I'm suspecting there's a bug somewhere in the Windows version, but I want to see if it gets confirmed here.

Later, I'll have more energy to write about this five-month long game. I could've had 55.6% of a kid in this time. Well, not me. I lack the required biological components for that development process.
