Arrow keys to move. Mouse to look around. Collect green particles for score.
I mentioned that I might continue flying.io Rather than continue, let's evolve it Here's flying.io in space with planets Planet artwork from https://opengameart.org/ Think of planets like bumper cars. Maybe green particles, instead of being score, is energy and when the max energy is reached, you become a stronger planet, this repeats endlessly. Stronger planet bounce weaker planets further. There could be objects like the sun that destroy planets nearby. Stronger planets could bounce weaker planets into the sun. Stronger planets can become weaker since energy drain increases with each level. If energy reach minimum energy for a level, the planet becomes weaker. Planet that are destroyed by the sun, give up half its energy to the attacker.
