Heard the hype about it so I thought I'd check it out. Pretty cool for open source. If you have trouble using this release on Macbook Pro with Retina display (OS X 10.8+), the following worked for me: 1. In Displays preferences, scale down the resolution (so text is bigger) by one setting. 2. Run the game. For me, it appeared, full-screen, in a small portion of the screen on the bottom-left side. When I moved my mouse above that portion a few inches, I figured out how to get the game to think my mouse was over the buttons (fortunately they have hover effects). I had to move the mouse to a Y-position a few inches up on the screen from where the button actually appears (but the X-coordinate was correct). 3. Adjust the settings so the game runs in Windowed mode. Save setting and close the game entirely. 4. Return resolution to normal. 5. Re-run the game. Worked fine then.
