How do I get a curvilinear projection like 'Subway Surfers' does

Hi everyone, how could I implement a curvilinear projection like the game ‘Subway surfers’ shows bellow? I tried using FishEye effect but it seemd very strange no matter what parameters I choosed.

Can be done with a vertex shader that offset the position of vertices in a quadratic curve fashion based on camera distance.
