Disclaimer: I fully understand this is a game jam game not everything can be done but even then I give very "tough" feedback so if you can't handle that kind of "criticism" it's ok just don't read my message.
There didn't really seem a way to lose? Atleast not one that I found.
The Menu buttons are quite small (atleast on browser version) so you should watch out for that..
There's no feedback whatsoever with hitting anything, all I could "feel" I think was getting pushed back by cops and maybe cars too?
The Score is kind of not very visible so I would recommend first using a pixel font if it's not being used because of this being a game with pixel graphics to have consistency, second to add "flavor" to the score text, for example when you gain score it tilts and grows and then goes back to normal, make it colorful (but do be careful with not too colorful/bright/dark), etc.
The game itself lacks a lot of juice, endless runners tend to be carried by all the juice (it does depend on the style too) but yours could benefit a lot from it (if done correctly)
Consistency is key, and the cops sprites do NOT go very well with the rest of the sprites for example, another is the "fans" people sprites vs the "background" people sprites seem very different, if you're using placeholder/free to use assets make sure there is atleast some cohesion and consistency with styles.
The music is not bad but it is somewhat loud and also there's lack of sound effects so should be careful with that for next time, don't leave it at the last second, same with the menu
All in all nice running animation, you managed to submit and publish, good for you, just keep these things into account. Even endless runners are harder to make than they seem to be
