It's a good game.
Like most escape games the quality stands as amazing. Not something to be surprised though seeing that a lot of escape games these days have this unique trait. But it does seem to stand out a bit from the rest.
I found the game somewhat easy. Not bad, probably just me though. At points I must say I was a wee stumped.
It's very good that you added a walkthrough. For some frustration is common in these kinds of games, so it's good to add a way out.
I see you're going with the normal escape game with the average house room escape. Using the living room isn't bad, but I suggest doing something as your own unique idea. What would really get the attention of the gamers is if you added a story line along with it. Some visual they can get. Who is this person? Why is he here? How did he get stuck? What is the main reason he wants to get out?
Ex. Making a game such as escaping work. A young co worker. Who went to work one Saturday morning. While in the duty of his typing he fell asleep getting himself locked inside. What he needs to get out before the boss returns next morning.
Doing something as simple as that would not only increase your score, but you'll have a lot more people coming back for more.
As house rooms are as common as the average teen pimple, you should create your own idea. Whether it be an office, or after a failed attempt to rob a store at night, you now face the conflict of getting out.
There is plenty of great ideas out there. Looking for the right one may be hard, but it certainly is rewarding.
