You should add like a highlight effect in the main menu when you hover over the options.
I like the story, this game has a lot of dialogue, and lore in the game itchio page.
The gameplay is pretty unique, i like it.
The only issue i have is that i don't see a reason to have lives, if you got it wrong by accident maybe it's helpful, but if you forgot what the combination is then it's useless, and since you don't have to start the game from the start continuing is the same as retrying but the latter is better since you can see the paper again.
Overall, the game was pawsitively enjoyable and whisker-tickling fun, even if short.
