I played this game so much as a kid... but never got very far. I'd always inevitably get stuck somewhere and I could never figure it out. It wasn't until I played the game probably in my 20's that I actually played it all the way through! Such a fun game though, with some interesting mechanics. You used a magic force/magnet ability to pull things and solve puzzles, and eventually you can switch between your normal character and a knight. If anyone has an emulator I highly recommend!
(edit: oops my bad, this should be in 16bit!)
So it's an action adventure game sort of like The Legend of Zelda series? I shall add this to my growing list of RPGs to play!
