This game has a lot of potential, but the physics kind of destroy the fun. I'm not expecting the physics to be exact, but it seems like some levels are impossible because the physics for certain parts launch your coaster halfway across the level. It makes it very frustrating because you seem to have a good idea in theory, but the physics don't act the way you would expect them to.
I understand this is merely an advertising game, but it seems a rather poor attempt from Ubisoft. I was actually excited that a AAA company decided to get into the flash biz, but this is obviously just a ploy to promote the new movie. Even so, Ubisoft could have easily spend a little more than $10 and got a decent flash game out of it as well. Heck, give me $100 and I would have done a much better job. This is a sad excuse for a game, especially from such a well regarded developer. I would have expected this from a movie company but not from a company who already develops AAA titles.
Great concept for a great game and its looking pretty good so far. The game definitely needs a lot more polish though. I would consider tanks falling over and flying halfway across the screen a major bug that I saw at least three or four times during game play. Also the AI seemed a little off in its shooting trajectories. These things, although small, affect the game play enough to where I did not like the game as much as I could have. Overall good job though.
