I can't pet the cat? 0/10
For real though, I had a good time playing this game. The game is essentially spot the difference, but the addition of the memory elements makes the game pretty interesting. The success streak mechanic and door locks add stakes to the choices and makes the game more challenging in a good way, reminds me of Exit 8. Also nice job on implementing the theme here, many games tend to focus on only doors but you managed to see 'what's behind' and mix it into the core gameplay.
My suggestion would be adding signs ( =, =/=) above the doors. Left and right seems a bit arbitrary and it takes some extra effort to memorize them, which is far from the core gameplay. Also maybe you could add more variations to each rooms as player progresses, such as different floor patterns, to keep the gameplay fresh.
