is there an easier way...or some pointers to get pass the alternative reality level?...the one wehre u got to pree the right keys and all to get away from the giant bugs...because i keep failing the last one...i've tried sooo many times!!!....just cant get pass it....

well here's a suggestion, go to the options menu and pipe down the difficulty level. Now you get more time to press the buttons before they fade away. By the way, that's what I did as well after half of the game. This way you also get more time to enjoy the action scenes, most of them are really great but you can't really catch them because of the stressful button pressing.
Enjoy

Or... you could always try not to be rubbish. I failed once. ONCE!!! on normal mode.

2 simon sez sides. make controls wsda for left and add arrows for right side. So yellow is d or right arrow depending on screen. Takes two hands. Took me awhile to figure this out myself.
