Nice game! Cute idea for a stealth game.
I'd give your player a map, since the child would probably know all of the house by hand, while we don't. Also, the "patrols" are a bit easy to avoid. Either add more (like an older sibling, for example, or a grandparent that stays in one place but can fall asleep for a different patrol behavior - similar to cameras in Metal Gear Solid) or make their paths change between each "mission". As of now, it's very easy to clear 2/3 objectives in a row without even coming across one of the patrols.
To be fair, the worst problem of this game is that it finishes too quickly - which is great for a game jam, but makes me want to play more. And that's honestly a great problem to have!
All in all, I enjoyed this submission! Great job!
