thanks for playing our game! Initially we concepted the cat as being a secret agent and you would instead hack into the humans laptops, but settled for rattling through trash.
What's not explained about the game (our fault) is that the top bar is how awake the Human is, if it fills they chase you around. In general it's supposed to be 10 interactions with the trash to get a key, but the key counter is also broken. If I could do over it would be one interaction, the trash disappears, you get a key and the human is immediately chasing you.
