Flappy Gopher

This is a modified version of Francesc Campoy's flappygopher.

Features:

• Pipes are generated in pairs (top and bottom)
• The distance between pipe pairs is constant
• The gravity is stronger, and the jump a bit stronger
• It uses a neural network to react to the game input
• It uses an incomplete implementation of genetic algorithm to evolve the AI

You may need Rosetta to run this on Mac.
