Okay I gave it a try. Thanks Pete. I agree, the catch is the stupid energy bar. Figures...
However, I must say, 5 levels in, I do recommend it (at this point). Energy bar aside, the puzzle aspect seems fun. I haven't gotten to the tower defense battle part but it actually unique in the way that it's mixing a defending/attacking/puzzle game into one. I haven't hit the actually defending yet but the videos in game show me what's to come. I hope it's good. I'm only worried about unlocking and IAP. Some games do it worse than others.
Also I really enjoy the design A LOT. From a graphic design perspective, everything is great. Animations are wonderful, the UI is nice, the start game screen using the movement of the device, and the over world map. Everything looks beautiful. But the game itself will require more play.
Btw also take note that since it IS a puzzle game, one of the big problems is gonna be burning the energy bar really quickly. Quite clever of Ubisoft to develop a game like this to take advantage of that. I burned 8 bars in 5 minutes because of failing to understand missions. However if you are a mega puzzle genius, ignore my comment.
