Protip: After pulling a blue string, you can push it instead of simply letting go. This launches your shape! Also, to a comment prior to mine, Eva shouldn't snap blue lines, as her corners are somewhat rounded.
Sometimes it cheats you, but sometimes you get really lucky! I just had a blowout round: 10500 to -150 in 5 turns, all that frustration has been repaid!
i played back through another time to see if there was some kind of different ending if you had all the gems, i was dissappointed... oh andone question: why the heck am i a snowball!?
