hey, in the Mac version the character does not move at all. not sure why
Hi. I'm also on Mac. Just press the "Pause" Button. It seems like your game is paused when you start it, just press the pause button to unpause it and you should be able to move the player around. If that doesn't work, press it again and try if you can move the character. This works for me, I hope it does for you too :-)
