Black, no sugar

As a true coffee enthusiast, you cannot allow those sugar cubes to fall into the cups and spoil the pure taste of some good, black coffee. The task, however righteous it may be, can prove exhausting, so keep your caffeine level and your speed up by hitting the coffee machine as often as needed. More sugar starts falling as your score increases. You only have 3 attempts, but one of them will be restored every 300 points. You can still catch sugar cubes very low in their trajectory. Do not give up...
