Funky, and very on point music. Game is interesting, but the physics aren't the greatest (ie. the olive moved horizontally out of my cup), and the glass doesn't stay where you have the mouse. You could make this doubly accessibly, by allowing the use of keyboard as well as mouse. Definitely not what I thought this would be, it's a cool, creative, and different concept. Nice job.
