I have heard of this game before and so i thought it may be a good idea to buy it... I am now 4 levels into it and i could barely take a break (my hurting hand seems to be the only thing to stop me). It is in a cool style, the levels differ a lot and the story is ...well there is one. BUT what i think makes this game awesome is the possibility to make TRIs(triangles) on which you can go, build further TRIs and so on. This is the best equipment/weapon/whatever(/why does my hand still hurt) in a game I have seen in a long time. And if you like riddles and hide and seek this is a must play!!! Would recommend!
