PGFM
I couldn't figure out how to pick up the Purple Gravity Field Manipulator. I tried spacebar, enter, shift, typing PGFM (sent me back to menu), W, A, S, D, Q, E, arrow down, and various combinations of these buttons. Up to this point, the game was great. I loved that the character was wearing a helmet. It made me smile every time I looked at him. Good choice of music as well; soothing, but not distracting. The only points you lost were due to grammar.
If someone could tell me how to pick up the PGFM, I'd love to finish playing through this game.
