Some sections are blocked by closed doors, and these require a key to open, which you'll find randomly scattered throughout the map, just like all the other items. One of the slightly frustrating elements of this game is the way the multi-screen layouts seem to hint at a certain configuration. I remember traveling down a stretch of hallway, with part of the screen walled off, and no entrance visible. I thought I was right around the corner from a door, but I ended up walking all the way around the area, with the entrance on the other side. On top of that, I was out of keys. This isn't necessarily bad design, but it's a frequent occurrence.

There are no other enemies in the game besides a blue dog/bear, who sends you back to beginning of where you entered the screen. Fortunately, the game pauses to allow this, and doesn't penalize you with time lost. The blue dog's movement is as slow as yours, and somewhat erratic, so you'll want to watch for him.
The only other problem I had with Yule's Christmas Quest was the constant refrain of the 12 Days of Christmas song. For one thing, you can't turn it off. It sounds like a MIDI version of the tune, which means only one voice. It might be a bit more bearable if there were more instrumentation, and, y'know, lyrics. Hearing the same melody played over and over again gets to be pretty maddening after a couple of minutes ... and then it starts all over again.
Given that these titles are both for the kids and freeware, I can't really complain too much. Your children will likely enjoy them for what they are.
