It starts out pretty fun, and it has nice pretty graphics except for the unskippable take off and landing sequences.
It seems like it should be a really fun game but the problem is the gameplay is not ironed out enough.
The major flaw is a basic game play thing having to do with understanding and rewarding the player.
If there is no point to it, if I feel I'm not being rewarded for my increased skill, energy, and, or understanding then it's just not fun.
A very obvious example: One would assume that if you only get a 3 star completion for a level you should be able to repeat the level well enough until you can beat it full stars. This is a common mechanism that you would naturally expect but apparently the game doesn't work this way.
This is what makes angry birds fun for example. You want to win the level perfectly and you get rewarded for it.
First it doesn't indicate to you why you didn't get a full star rating to begin with. Then if you repeat the level it doesn't tell you anything else. Even when I knew I played the level better I wasn't rewarded for it. Not a better star rating, just some credits maybe.
Now I'd take these credits and buy upgrades.
But then from how the game scales it automatically increases the difficulty (it scales) according to the upgrades you have.
So here one is trying to figure out how do I play this better, and, or, at the very least think with your new powerful upgrade you will kick some major-A in the level you can't.
Trying to best a level becomes a exercise of futility as you always stay one step short of it, and wrapped in mystery anyhow because you don't know what makes you better (other say doing well enough to pass one).
With this one mechanic sorted out it would have made me stick to the game longer then a few hours.
Also while it was kind of cute and silly, the game dialog wasn't really compelling to me.
Either poorly written, and, or, it didn't make sense to me in the focus/direction as a game.
Play it..it will be fun, but missing the potential to be the addicting game you thought you might come back to.
