P-Tapper by Milkymalk is a remake/demake of Tapper known from the Commodore 64.

You use Z to tap a beer. Holding the button will fill the glass, releasing it will send the beer across the table. The fuller the glass is, the more the receiving patron will be knocked back. If all patrons are knocked out of the bar, you win the level. Patrons have to be fully inside to catch the glass (nobody likes being served while he hasn’t even entered yet). Any glass that is not caught will smash and lose you a life.

When they finish drinking, they send the glass back to you. You have to either catch them, giving you a fresh glass (or loses you life if you fail to), or have the waitress collect them, which is convenient, but gives no points and you have to wait for her to return to receive the glasses.

You send the waitress by pressing X next to the bell at the bottom.

When the barrel is empty or close to empty (3 pixels of beer left), you press X while next to it to order a fresh one.
