You find yourself in the middle of a pretty town square in the centre of a nondescript New England town. You have absolutely no idea what you're supposed to do. Maybe you'll find something amusing and enjoyable to keep you occupied. Just don't pick up the phone booth or you'll die.
Notes
Although the solution to this game is very simple, it did inspire many sequels and imitators and was a finalist for the best individual puzzle in the 1996 XYZZY Awards. (The puzzles must have been pretty weak that year!)
