Hey, i just played your game and well it was quite fun actually !
I had a hard time getting used to the controls to be honest, but i had a goo time playing it ;)
The highscore system is also a very good idea to keep player interested
Now, i would suggest few things :
- make a fog effect not to see objects spawning but also not to see the end of the bridge
- make the controls a bit snappier
All in all, that's a good work :)
NB : I managed to score 2008 after few attemps
