Thanks so much for playing and providing feedback! The dog sniffs whenever he begins patrolling, but I forgot to spatialize the sound properly, so unfortunately it is audible map-wide. Agreed about the music change! We'd planned to change the music based on whether the dog was alerted or not, but wound up not having enough time to fully implement it.
Appreciate your thoughts on the gameplay! It definitely ended up being too simple. I have a bad habit of leaving level design until far too late in a jam, and then scrambling to put something together. For this game, I'd also completely forgotten to account for obstacles/pathfinding with the dog's movement, which certainly didn't help! Absolutely going to focus on planning and executing level design much earlier in the process in future jams!
And really glad to hear you liked the quacks :D
