Hmm... So far... uhmmm... I can't say it... haha...
anyway, the balance part was a bit hard to decide...
btw, I finished checking the first entry... ^_^
EDIT:
I would just like to restate my earlier statement:
leaks (especially those that are easy to clean) will result to a huge loss of points on the coding part... and no effort on cleaning leaks will result to a higher loss... (those who made via OE might actually have a higher score than those who coded/triggered but incurred lots of leaks... at least for me [and assuming a good output]... but ofc, complexity of the idea will still be considered)
