Good job to both of you! It's a cute and well made game. To think you pulled it off in just a week, being someone who doesn't know much about game development, I'm surprised by the work that you had to put into making something like this.
The idea of fighting for the last biscuit is entertaining, just the image of fending off so many hands is funny. Or maybe they are the same stubborn hands that keeps reaching for the last sweet treat, hahaha.
I also loved the way you designed the helpers and their power-ups, the imaginary scene of grandma's rolling pin smacking the hands and the neighbor's dog biting those greedy hands are just hilarious, to name a couple.
The progressive difficulty is handled really well, too, and the risk factor makes things a bit more exciting, it's difficult but that's what makes it fun (though I kept losing while risking, lol). Honestly, amazing work!
