The title sums it up nicely.
Also

The whole game is called Red and we used a lot of red so we used Red twice.
The controls are sometimes really "good"...... so yeah maybe you shouldn't always trust your instincts there. Maybe they are just easy to learn, hard to master.
We literally used the phrase "Fuck the rules".
Unicorns are so 2015 that we didn't use them at all! 
We subtly used the phrase Thanks Obama. Don't worry if you don't find it.
It's so post apocalyptic you won't recognise anything! It takes place in the Otter Empire.
The occaisonal flight is a feature.
