I am a big fan of Crazy Taxi so It was easy for me to get into the game. I don't know if it was on purpose, but I love how you recaptured the feeling of crazy taxy by exaggerating the turn speed.
I got an audio glitch throughout the entire game so that was a bit annoying, but I admire the efforts.
There were also a bit of framedrop but that is because it is a browser game, and overal it ran ok.
Also, my auto stopped in the middle of nowhere so I assume that I ran ou of fuel, but then I didn't know what to do so I restarted the game. This can be improved with a gameover screen or restart button that pops up in front of the player(or maybe I missed something...)
I also have to mention the camera, it is good! I advice slightly adjusting the field of view to give more a sens of speed! (How faster you go, how higher the field of view )
I it is funny how the NPC stand up after you ran over them haha.
Overall I think it is cool!
