I don’t believe in giving out the solution to a puzzle, only giving hints that make it easier but still allow you to say you solved it yourself. If you think a hint doesn’t help enough, reply and I will try to improve it.
General Tips
You don't need to solve the levels in order, they are roughly sorted by difficulty within each island, with the hardest ones optional in the corners. You may find upper jungle levels easier than snow.Don't expect to make constant progress, take a break and come back with a fresh perspective. When you solve a level and don't understand how, go back and analyze what you did to learn from it, this will help you tackle harder levels.
I’ve currently only been able to get Green to the fruit, as any time I try to get Blue up, it just results in the box falling off Green’s head. I have no idea how I’m supposed to get both to the exit without Blue eating the fruit, and your current hint doesn’t help me with that. Any help is appreciated :)
