Nice! I managed to get to the score of 8000.
It's fun to play and fun to try to beat your highscore. The visuals and the music are also cool.
I would suggest adding some randomness in the way obstacles spawn, because right now they all appear at a fixed rate, meaning that the game is kind of the same each time you play, and you end up relying on muscle memory more than on your reaction speed.
But overall, a nice entry!
