Most of the classic LucasArts adventure games (Sam and Max Hit the Road, Maniac Mansion/Day of the Tentacle, Monkey Island, et cetera) had it so it was impossible to die or enter unwinnable situations, believing that adventure gamers shouldn't be punished for exploring (as opposed to the sadistic but equally valid "Sierra-style" of adventure gaming, where doing even the slightest thing you're not supposed to will almost always kill you or render the game unwinnable). That's not to say LucasArts-style adventure games can't be hard, mind you, but you'll always be able to solve a puzzle at your own leisure.
Most of Telltale's games have followed this trend as well (although it seems like they're starting to stray from it. Jurassic Park will feature deaths).
Yeah, even the 2nd episode of Sam & Max: The Devil's Playhouse, you could die...but since it was on a projector, you just rewinds and try it again. Actually, Jurasic Park kinda does that to, you die then just back up and try it again.
