I went through your game, fun play style, and the theme of the game, moving the cans is just not convenient, it kind of crashes into you when you hold it in front of you, but so cool!
I added the pick up mechanic becouse of a friend who said the game was not funny enough and that came to my mind hahah but yes It is not necessary for the game and I didnt code it really well. Thanks for the feedback and for playing :)
