1)Placed throughout the game are energy drinks called "BLUDEVIL" that depict a devil-like thing with sun glasses. This looks similar to the publisher DemonWare logo in the beginning (which is also a blueish- devil-like thing) and could be a reference to them.

2) There is also a form of Full Throttle called "Blue Demon," and this could be a spoof, since Full Throttle isn't a sponsor of the game.
