Interesting game. Reminds me a bit of subway surfers.
Sadly the first time I played it it bugged somehow and the sky sign never spawned, so I was not able to upgrade anything. Luckily after the restart it started working properly.
Also I think it would work better if the camera was focused on the top part of the screen instead of the middle. This way I was not able to see obstacles or coins in advance and change directions quickly enough. That made it pretty much a guessing game (should I go left or right?). I also encountered a bug which blocked me from buying anything even though I had enough money.
Although most of what I mentioned above was negative I still enjoyed the game. The gameplay is entertaining and very addictive and the choice of the music is also great!
