Great game!

I just finished the game, and I encountered no problems whatsoever. I ran it on a MacBook Pro, and it did not lag as I feared it would (though I ensured I didnt have any programs open while playing), nor did I lose my save progress. The installation time was a tad long, and the battery drains quite fast when playing but it was well worth it in the end, and I have a feeling Ill be playing this game again!

If youre looking for a great game, I would recommend this wholeheartedly!
