Try catching red particles and avoiding blue ones to get more orbitals in both Run and Survival mode! The more orbitals you have the faster your score will rise and the more you'll be protected from Game Over collisions.
This game is inspired by electronic transitions in atoms due to interactions with photons represented by red and blue particles.
The sounds you'll hear on collisions are the harmonics of the C note and represent the electronic transitions frequencies.
Anyway by no means this wants to be a representation of what happens in nature, it's just a matter of inspiration.
