This is a RIDICULOUSLY good game.
The driving "mini-game" alone is awesome, let alone the platformer as well.
How on earth did you do this ALONE in the time period,!?
The graphics style is amazing (I may have to look into your Pixie game engine!).
The music is also really great.
The whole atmosphere reminds me of a mix of "Escape From New York" and classic (read: cheesy) 80's sci-fi actions films.
I almost got stuck at the end, coz I couldn't tell what had unlocked, but found the "cure" in the end.
Great stuff - good luck! :D
