Just played a few more times and it's a bit misleading to say the least.
At the beginning of the level, it says clear all the jelly and reach 250 000, but at the end when I've not cleared all of the jelly it has a cross next to the box where it says clear all the jelly and it puts a tick next to a box saying score 140 000.
I think what might have happened is, I cleared all of the jelly and scored over 140 000 (so it put a tick in both boxes) but I prob scored less than 250 000, so I didn't actually complete it, even though both boxes were ticked ........ oh well :(
