I can see the overcooked inspiration :)
It took me a bit of time to understand what process and to see the cups. When I found out it was ok. From my try I thrown many times the cup because I wanted to take it from the floor but I ended by throwing the cup because of the auto pickup. I imagine I got that from others games of that genre.
I searched for the commands first, it could be great to have it in the description :)
Nice job tho' there still a lot of tiny mechanics and screen/menu handling. Congrats!
