I enjoy it. I liked that there is some sound anticipation for the enemies, that's a nice detail. There are somethings I wish were different.
The default viewport size doesn't fit the game very well, in a 1080p monitor it cuts some parts of the street, I didn't understand the taxi part because i could barely see it, once I played in fullscreen, the experience was better.
One flaw in the score system is that its incentive is a little misleading. The score seems to care only about time and not over distance. Which would incentivize a slow play as a way to optimize score, while I think most of these endless runners are more enjoyable when moving fast and getting farther away.
I didn't like that the bonus of hitting 3 birds is an active action for getting 1000 points. It would be better if you make it either as a passive score bonus (i.e. after hitting the three birds, instantly give some bonus points, visual effects for this would be nice), or an active power which does something like invulnerability, or something similar.
Looks like there is a bug on the leaderboards. The first time I played, the list was showing my username with a Score I didn't get, when looking at the list again later, some other player (probably the correct one) is listed with the score I saw before, but my score was not present in the list.
Hope that reviewing sooner than the deadline helps you to improve some of these points I've mentioned.
