A very pretty endless runner.
I was very fond of the audios and graphics I must say. Especially graphics; the low-poly models, combined with the lighting effects, looked pretty in my opinion. Combined with the synth sound effects of switching your direction, going lower, and collecting the orbs, created an ominous atmosphere, which I really liked!
As to gameplay, it could have been much better. I think, that due to the perspective, it would be better if you would control the orb with the up-down controls, rather than left-right ones. Also, due to the previously mentioned perspective, as well as slowly rising speed, and the poorly implemented controls, it was really hard for me not to miss at least one orb from the spawned orb clusters.
Overall, it's a game with a really nice minimalist graphics, and a great atmosphere, however, I think that the gameplay mechanics, need to be reworked. But still, you've done a decent job!
