Oh I loved this one!!! Really coo puzzles! Right now I'm stuck in the 2 last levels but I want to finish this!!
The only bad criticism (I recomend you to use this tip in all your games); the game controls are keyboard driven so I recomend you to change the map controls to be keyboard driven too; it is a bit annoying to change to mouse. If you do a mouse-driven game dont make the UI/map/level selection keyboard driven neither
You can try our game too, it is some similar kind of puzzle you may like it!
