Mixing references to pop culture ("goo goo gjoob"), classic literature and adding a time-travel element on top of it all, T-Zero is a very difficult work of IF to classify. It's about what you might expect to get if you were to combine a well-schooled English teacher, a mad scientist, and a professional comedian.
The puzzles in T-Zero shine like polished gems - which is a good thing as they are the mainstay of the game. "Nord and Bert" aficionados will have a definite head-start over other players, as will serious bookworms and those who paid attention in their English classes.
Nuttiness aside, the game can also be great 'serious fun' for the thinking man (or woman) with the occasional action sequence to spruce things up. Waiting patiently for the right time to come at certain places will bring great rewards...as will outrunning a giant boulder Indiana Jones-style.
From the ingenious use of certain mirrors to navigating the fiendishly nasty topiary maze (which took me over a year to beat), this game is anything but a zero!
