Bonte must be bemused by all the comments asking for a speed up button... it must be the sugar rush. To me, the game is an exercise in focussed relaxation. Jus' chill an' take some time out...
Some tips: 1/ once an area or cup is filled close it off 2/ make funnels into the cups 3/ make little buckets above the cups to fill up so when you change gravity they fill the cups 4/ draw around words and obstacles so sugar doesn't get trapped 5/ brush your teeth twice a day.
Definitely 5/5 ( would be 6/5 but it gives me toothache, ouch!!! :)
