Haha, awesome! Still, there is no more content after that. I thought about adding a list of phrases after red, like every 100c or 1000c something like "you still there? please leave" and funny fourth wall quotes like that, but I felt like I'd be wasting people's time.
I might add "distance" though, like after the speed of light is reached, a progress bar reaching several milestones, like the closest star, the center of the galaxy, the edge of the local group, the edge of the observable universe and so on... and an achievement system to unlock those, so it's actually more content to keep you engaged and not just a phrase or a background color.
In any case, I'm glad you enjoyed it, thanks for playing!!
