Like I said on Mari0's forum, love is broken on OSX 10.9. More details on that post. I will wait for you.
So, before I present you my "fixed" version of the Ortho Robot, I must warn you that this game was made using love 0.7.2, and my fix consists in use the fixed love 0.8 for Mac. I have played a little and had no problems but it will give you an error when you try to close the game.
Remember: this is my try to temporary fix it until Maurice (which is 42 million times smarter than me) officially fix the game.
Here you go.
