Thanks for the hint!  It got me going.  It still took a little bit of time to figure things out but I eventually made my way upstairs(?).  And then down to the basement.  Quite the psychedelic trip downstairs!  And who knew the crazy scientist was (gasp!) Tony Stark!  LOL!  Good job!  Lots of red herrings too (like the garage, what's that all about??? There's nothing of use there.) Overall, pretty cool game!  Oh, and did I miss something?  I only found 4 of the 5 items and I was still able to beat the game.  I have no idea what the DVD was for.  I assume the gold coin got me upstairs and/or downstairs.  Just curious.
