Hmm, it seems to work fine on my little Macbook Air. Did you get any kind of error message, and did you give the app permission to access the other files in the zip?
I've recently started a new challenge, where I create 10 games in just 10 weeks, one week per game. See my blog post for the rules.
The first entry into this challenge is Sticky Golf, a game where the obstacles you hit stick to the ball. It's silly, it's chaotic, and I'm pretty happy with it for a week's worth of work.
