The game is really cute. I love your sprites.
Some of the villagers seemed to be able to move through the house. I wasn't sure if that was intentional or not (so that it would let the player know if they are going in the front door and exiting out the back, etc).
Some kind of warning for when a villager is going to exit the home would be neat so that the player can try to plan not getting trapped.
Great work!
