hope, that TellTale Games visiting this forum, and if they are not, I'll send them a letter (through my TellTale account).
So, let's write all game bugs you saw in game.
-Light. Sometimes Max become Black on the roof of pizzeria, and another places.
-Pieces of models are viewed. Example - Max's body got shadow on one part, and dont have on another. This makes stripes on him.
And whatever, I want to talk about another thing. I know friends, who have bought S&M only for TF2 items, so they completed game without any interest. Another friends completed game for "competing", without any talks, clicking on the objects and even skipping all the diologs! One friend didn't saw Sam and Max inside of Max's brain! (First teleportation).
How change this? Achievments! Steam achievments is great thing! It can motivate people for finding objects, talk more or even complete game more than 4 times! You can make achievments like "Don't skip any diolog" or "Watch at all possible objects with Futurevision", "Talk all diologs" and another things! Moreover you can hide something special and make an achievment like "Find XXX". This is always interesting and everybody loves achievments!
