Oh wow, that's a very original concept that is PERFECTLY in the theme! The idea is really good, the execution is awesome, and even if it took me a while to understand everything, that was quite fun ^^. The furniture physics is soooo satisfying, and I juggled a lot, even when it was not needed xD. The music and sound design is really good, the UI is juicy, everything feels soooooo smooth, there is a LOT of effort put into that game and it shows!
Now... I have one complain about the game ^^'. My first run was painful, and I quitted the game right after my first loss, frustrated and lost, with absolutely no intention of coming back. I don't understand why the floorplan is not accessible from the beginning. That's just a really weird design choice, how am I supposed to know which room is linked to which? It felt like playing Magic the Gathering, but without knowing the effects of the cards, just putting stuff randomly on the table and see what happens. Huge thanks a lot to the comment below me that mentionned that there was a floor plan! It made me come back to the game to check it and I finally could enjoy it. In fact, I even played with the screenshot of the floorplan on my other screen, and the game was way better like this. Why there is not a "floor plan" button during the game to show it is a mystery to me. Having to memorize a plan is not "fun", at least not for me. You crafted a beautiful difficulty curve, your game doesn't need such an entry barrier ^^'!
Ok, sorry, that was my "complain" paragraph, let's get back to compliments ^^. I had a blast playing this game, and I was amazed by all the little things you added in such a short time. You didn't have to add the "knocking twice" mechanic, you didn't have to add a "room spawner" to play with the physics, you didn't have to implement such a complex score system, with bonus reward for speed, you didn't have to give the door some collisions when it opens so it pushes the furniture one last time, but I'm so glad you did all that! This game is made with love and care, and it shows in every pixel of it. That's amazing.
Congratulations =).
