I just played this game that's rated one star of difficulty (out of four) and I still had to cheat once to get a key.
It's a cute little game where you have to collect all the presents and unlock the door to leave the room. The instructions don't say that sound is required, but it makes the game a little more fun.
Click to go to Christmas Escape.
hints: sometimes you need to stand back and click under something to see what's down on the floor. and some items lift up and some you look inside (or both). you need to build a fire. click everything. the plant is thirsty. examine the thermometer after you start the fire. there is a correct time for the clock (look for the two sets of hidden numbers). and yes, I collected all the presents.
if you're really stuck, some cheats are on this page.
