Ok, finished it on my 2nd session. Maybe a little over 2 hours total.
By the end I liked it! I think the first half of the game is kind of weak. Really linear, almost no puzzles, controls are kind of funky at first. The 2nd half when it opens up though is great. Fun puzzles, fun environment, great pacing.
The ep is waaaay shorter than Telltale's usual stuff, but otoh, the pacing is MUCH better. Their stuff always drags (I hear they started getting better at this with Tales of Monkey Island but I still haven't played ep2+ of that). I figure you spend $10 to see a 2 hour movie these days, so a well paced good game for $5 ($25 season / 5 eps) isn't too horrible.
I'm a little surprised by the ep2 preview.

I had assumed the way to do a BttF series is that every ep has them going to a different time period. But it looks like the entire season will be in this one time period and if they do more seasons, each season will be a new time period. Just hope they add a lot more to the environment. The game scope was really small, even for a Telltale episodic game. There were very few rooms and only 1 real location.
Looking forward to ep2. Maybe I'll play the rest of Monkey Island while waiting.
