I much as I like this little adventure and all its glory and greatness, has some very annoying game flaws. Accessing and upper floor you never know where is the next platform (I tried standing still and jumping straight up than moving towards area) and you fall back, all enemies respawn and they eat you. This can be such a pain in the back on hard difficulty, but the responsive and... perfect controls make up for it :D. Great music and the enemies are simply, well designed. I like the added shooting action to the "turbo tunnel" part, f$@#awesome! Id gave u 20 if I could.
