The audio was well crafted for this. The music sets a nice old school mood, kinda spacey-carefree. The SFX were nice as well, although I'll have to admit that the intro dialog was skipped as fast as possible for me. That particular tone was very ice-picky. The other comments have already mentioned my feelings on the boost. I would remove "Give Up" as an option. It is too easy to stumble upon.
Overall, great entry!
