I don't work at Oxtord Games but I'll try and help you, there's no way of hacking the points (atleast I think), let's get this item you really want.
-1 Don't buy anything on the first 2 levels, just what you need.
2-On the 3rd level I reccomend just 3 scissors, and if you can a flashlight, nothing else.
3-Always focus on the items to use the flashlights less.
4-To get more points, go to Ms.LemonS and play her game to afford the "High-Tech Blender", it will give you more points for blended items.
5-Try and give him food as fast as possible, it will give you more points.
If you still didn't manage to get it, answer these questions;
1-Is he chewing?
2-Does the game stay dark after a (successfull) round and comes back to light when you get it wrong?
Remember tho, I don't work at Oxtord Games, so I'm not a professional.
If you need more help add me on discord Lino#5541.
