I think I'd like the idea of a quadrocopter game more if it was more like the calssic Copter games than that Flappy bird-type jumping control. Combined with both large obstacles, and a large copter, it makes for some difficult hit areas too, just feels way too easy to collide with things and start over. Also a bit blank background, with more than just stylized obstacles, it feels like it could use a background too. Function-wise, it works well though. Keep it going; looking forward to the Copter-like mode!
