On one hand, I hate the fact that it's *yet another* Flappy-style game, but on the positive note at least your choppers are a bit different from those wall colliders.
However, the graphics seem quite lazy (why not have the tree backgrounds be transparent? It's a minute of work and a ton of improvement)
Also, it has a gamebreaking bug - if you just let the chopper fall down, you can get any score you want as there is no floor collider.
Hopefully this is not too harsh, but honestly, this doesn't look like a finished game.
(also, I've fallen off the game screen and am gathering points while writing this... since I can't come back up with a few clicks, I suspect the game will crash eventually, when my altitude overflows?)
