Trine2 w/Goblin Menace

Well my first time through the levels, I too had some problems, but nothing that eventually didnt reveal itself as my own inexperience with the game. BTW, if you do experience an issue and no one else does, then it is probably an issue with your Mac setup and-or equipment.
Anyway, some things that you might consider taking into advisement are:
1- Firing explosive arrows or using the hammer throw into areas where you cannot yet see ( in the distance to the right ) can destroy the enemy, but may, also, do things like knock a valuable cable trolley off its cables, which cannot be fixed without restarting the entire level. At first I thought this was a glitch, but it is not.
2- If you want the ability to float on boxes, then you must go to settings and enable that ability.
3- Lots of computer memory, and a really good graphics card are invaluable. My ATI 4870 w/512 Mb works like a charm on my G5 early 2008 desktop.
4- Be sure to carry things (when possible) from one level to another; like pipe plugs/caps, large rectangular stones, as they can often prove invaluable. Some items can be carried 3 levels.
5- I wasnt able to get an xbox 360 controller to work on my machine, but was still able to finish all level configuring the keyboard settings and using an Apple laser mouse.
6- BTW I am 65+ years old and not the quickest player in the world with my hands, but if your mentally sharp you can still win all levels.

Great Game with a well thought out design. The price is excellent too ! Bravo !
