City Runner

Really good concept. You could develop this into a solid game. Currently, I see two problems. 1) Building placement is too random, and you sometimes generate way too many building on top of each other. To fix this, you might have each new instance of the building check to see if it collides with another building; if it does, delete the new instance. 2) The jump ability is critical to staying alive, but it's hard to tell your altitude. To fix it: add a blob shadow projector under the player.

You can move downwards and never be caught by buildings)
