I'm thinking of doing another short game, and I'd like a suggestion. Which would be a better idea, an implementation of a hand-held teleporter, or something more interesting, an implementation of something like the Portal gun? Fire it in a room, it activates a portal (which is not yet open), go to someplace else, fire it again and it creates an open Portal to the other room (and that room now has a portal to this one.)

Given that Valve seems pretty cool with Portal "remakes" done in Flash and stuff like that, a well-done IF homage to Portal would probably be pretty cool. That said, assuming your game takes place in your own game world, having a mechanic that recalls Portal like that is probably a bad idea.

I don't know what you're thinking of for a setting, but in a Star Trek like environment, I think a hand-held teleporter device would make a teleportation system more interesting and believable. Being able to just beam almost anywhere is too unlimited; if people have to be holding a teleporation device to get "beamed", that would put a reasonable limitation that could aid storytelling and the setting. Maybe like the "thumb" in Hitchhiker's Guide to the Galaxy.
