My Project 1 Idea

For my NYC app, I want to create a simple mini game. It's a 2d side scroll game (run and jump) instead of 3d where the players have to survive. The goal for this game is to have the player to reach the exit from other side and to avoid any objects such as dogs, people, moving cars, etc. I want to create a pixlated 8 bit game because I enjoyed in creating a classic old school game. The players will have 3 lives. However, if the player louses 3 lives, the player has to start over to level one. Also, each of the levels will show a background will be based on the NYC setting (not sure what kind of setting, so i'm researching the background photos from the internet.
