Nothing too new or interesting.
What a shame. This game has the potential to be really awesome.
The way the back end of the screen gradually encroaches is stupid. Simply put it is stupid. There is no eloquent way to word that.
Also the stalactite/stalagmite obstacles are almost impossible to differentiate from the background. Even when you're going at a good clip you'll fly into one of those obstacles because they just don't stand out.
I'd much rather be playing Canabalt.
The good notes is, the game is incredibly smooth. And is VERY visually appealing. I had to score this game a 2/5 because due to its many shortcomings it is nothing too new, or interesting.
Make a few tweaks and release a 2.0 and you'll have solid gold on your hands.
