Graphics are decent, you can tell the coffee from the sugar. You use the mouse for the controls, so that works well. How long are the rounds supposed to be? I played round one and killed 240 sugars, and then I was bored. You should either add a time limit until you win, or the number that is needed to complete stage one at the top of the screen. Also, you should translate everything into English. Those changes should help this game improve.
