It's good...
It's good game is smooth and everything but the hit box for the birds is too small; i had to click mash on the birds many times just to get a point.
instead of arrow key try to make it for the 'WASD' keys, so then when you add more things to the gameplay then you have more keys at your disposal.
it's good and it needs a little work, but other then that it's worth the work to make it better.
