Fun little puzzle game, I really liked your take on the theme its very unique compared to all the other entries, nice job!! I never thought about interpretating it as finding one room among many and I think that's a cool perspective on things. The premise of finding the correct hotel room made for a funny context for the gameplay too.
The gameplay itself felt like an innovative take on minesweeper (as another comment said), and I think you could borrow from the minesweeper concept to help the logic in your game. For example, in minesweeper your first click is always an empty tile, you never hit a bomb on the first go. In your game, sometimes the first door you click is already occupied by somebody and you lose which feels unfair because there is no way to use logic to avoid this. Sometimes minesweeper will auto clear tiles if you click in the middle of an empty section of squares which helps the player avoid situations where the logic does not help them. For example, sometimes I clicked 2 doors in your game and the resulting clues didn't help me where to click next. Maybe auto-opening a couple other doors would help give the player more clues to use their logic on. I'm not sure if that made any sense but I would recommend playing minesweeper for a bit to see what elements you could incorporate into your own game.
That being said I had a fun time playing your game. The logic puzzle aspect was really interesting and the hotel environment was a funny one to fit the game into. The presentation is really clean; the colors chosen are great, the little particle effects when walking by a door were a nice touch of polish, and the wavy animations on the text were cool too. The stick figures fit the overall aesthetic perfectly. I loved the way new floors stacked on after each level, it made for a very natural progression of difficulty and fit the hotel concept nicely. And you had one of the best theme interpretations that I've seen thus far. Cool puzzle game, and keep up the good work!!
