Funny. 3 stars for that.
While I really enjoyed your Gravity Den (for me it is awesome), this one is definitely not. The controls are badly responding, it seems for me that you used a similar mechanics as in the Gravity Den when it comes to changing direction, but while in regard to the gravity it was reasonable, here it is not. You for example have a feeling that when you reach one point towards the border you can press/click all you want, but the guy won't change his direction like he was being attracted by some kind of a magnet. It is no problem when the gate is in the middle, but what if it is near the right or left border?
About the mechanics and controls: since most of the people are complaining about them and you even did not respond to any of those reviews...
Too hard to control. One star 'cause the pixel art is alright.
this is flappy bird on steroids.
