This was a fun one, I have mad respect for people who go 3D for a 9-day game jam! :) I liked the flow of the intro part, the aiming was smooth, the level design was great. Aside from the lagging issue on web that people already mentioned, I found that it was sometimes annoying that someone was shooting at me, but I wasn't yet seeing them, only could guess their general direction. Also, when I picked up a speed-up on the street level, the camera wasn't able to catch up to my speed so I didn't know where I was and what I'm shotting at. Overall, the game was fun, but could use more polish.
PS: I just kept playing and somehow rolled outside the level:
