Visually attractive, and the verb coin works great, but the PC doesn't feel like a bear waking up who needs to get his breakfast and needs to get to work; he feels like a generic adventure game character. The PC doesn't sound like a bear waking up etc etc etc; he sounds like the game designer coming up with things for adventure game players to read. Worst of all, this is not a house, it's an adventure-game-puzzle-place. Case in point: why would there not be an option to open the whistle case? Instead you have to do something with no motivation and which is something you're quite unlikely to do with something you own and it's in your bedroom right next to your bed? It has all the hallmarks of An Adventure Game Puzzle That Doesn't Need To Make Much Sense So Don't Think About It Too Hard Kay Thanks.
What the game has in visual charm, it lacks in character - in a way that interferes with solving the challenges. I mean, who except for an adventure gamer trying things out for no reason would do what I previously said on their own house without even trying to open it first? I got to it because I was strating to brute force, and then I spotted a connection, and I told myself "no, surely not, that can't be right", then I went and tried it and it worked. I can't call this good design.
