Was a small, but a really enjoyable experience.
This project is the perfect example why polish matters... I really loved how well polished it was.
But there are some stuff: - The SFX volume is too low, I can't almost hear it; - Maybe you could change the skybox color with the "color's level" or something; - Add a small splash with the logo at start of the game at least, that disappear after pressing any key or something, and then the game starts (can be in the same scene);
Good job!
