Okay, so a few things:
The game is stunningly beautiful in graphics, colors, layout, everything. However it gets ruined by its lack of progression, intrusive ads and no return incentives.
Lack of Progression:
You just go until you die, then start over. Another Flappy Bird model. You don't level up, you don't upgrade, nothing. Plus the game is hard to start out! You just get going and the direction changes and obstacles pop up. We should be eased into that.
Intrusive Ads:
WOW. I have never seen anything like this. Usually ad banners will run along the top or bottom of the game. Not here. About every 3-5 deaths an ad pops up and starts playing a video thank you have to watch for at least 5 seconds before you can skip it. But even when you skip it the app pops up a screenshot of the app and tries to direct you to the App Store. Knock. It. Off.
No return incentives:
You never level up, you never upgrade, and what's with the skeletons? Cool graphic feature but there seems to be no point in going out of your way to collect them. You can't do anything with them. It would be cool if you collect skeletons and use them to buy vehicle upgrades.
So, right now, 2 out of 5.
