Don't flatter yourself
Basically an Atari game with 3D graphics. A recommendation: give a bonus for going through the small gaps in the walls. Often times there will be an obstacle coming at you with a small opening you can fly through, but at the same time there is a larger opening around the edges and it would give the player an incentive to take the harder, more dangerous route if you got bonus points.
Also, I don't know why you called it "an emotional flight" in the description. Don't flatter yourself pretending this is high art
