The mouse is in fact cute. I think the biggest problem is that the game isn't managing the Z order, letting the mouse appear over some environment and props can help the space feel tangible, clipping behind something that you should be in front of feels bad. Making the player enter the room at the entrance they used would also help the game feel cohesive. I stole some bread in the beginning but I don't really know what to do next. For future games I also suggest making a web embedded version of the game, it let's players play the game without feeling like they have to commit to it, you'll see a lot of the games with a lot of rating are web based for this reason. For a first GWJ this is great, keep up the good work!
