Good game, just a few play through problems
First things first- I enjoyed this game a lot, and as it is part of the Game Jam, it works very well. That said, two problems.
1) You should make it clearer that you can't go outside, like the Bears can. It gets too easy to get trapped if the player doesn't recognize that fact.
2) It is also too easy to get trapped when the Bears are coming from two directions. At that point it becomes practically impossible to win. And as there patterns seem to be random, it is hard to avoid this situation.
However- the game was simple controls and easy to use. A little more work, and it would deserve a 9 on my scale.
