Wow, such a great game, I loved it way back when I was a kid.
The characters are amazingly manic and amiable, always making me smile, while the story is really funny. I always liked to operate in different times and change the future by acting in the past.
The only drawback is, that a few puzzles are kind of random or even illogical, like the important part how to free Laverne. But I never cared.
After seeing it here, I replayed it (had the disk version in a dusty box).
Took me like 15 minutes, because I remembered nearly every puzzle.
I hope they'll finish the fan project DotT 2 soon, looks great!
