Gersen: Now if they could just add this little thing in it... how is it called alredy... ah yes : gameplay.
Personally I have been very disapointed by this first episode, it's first supposed to be a game not some low budget animated movie. (speaking of which, as a BTTF fan I find the time jump sequence to be pretty lame)
There isn't any chalenge, not any real puzzle (by real I mean some where you have to actually think), just go where you are told, talk to the character and voila it's more than enough to complete all the tasks even those you haven't yet received and it's very short even by Telltale standard.
I havent yet played episode 2 yet though so maybe they improved things.
Basically my thoughts about the episode as well.
