Elephants meet k'nex
The controls are very simple and easy to master.
I'm not generally a fan of timed challenges but you dont really need to pay attention to the timer unless you're going for a high score.
In a few levels its difficult to judge the placement of the supports, sometimes adding to the fun of watching things go wrong.
Graphically the game is very impressive for $4.99 only a few rough edges here and there but youll hardly notice as youll be more concerned about the mice (you'll understand.)
Go download the demo and try it out it's well worth it.
