The game is quite fun to play!
Feedback. The 3 hearts are a little bit misleading, it could probably be changed to stop icon or something related so player knows that it is connected to missing the stop signs. And you could also add a boost button that speeds up the taxi to make the game much riskier and gains more points (optional button but it makes the player be more active than passively waiting for something to happen).
I still enjoyed it nonetheless and it has that arcade feeling on it. Good work again :)
