Elaborate on Intro-J. For such an early level, many people are stumped.
Getting the banana is easy. Create an L-shape when your snake heads inside the crevice, so that your other snake can push the handle left and let them escape. You now have a 4-snake and a 3-snake.
Getting the grapes is possible if you’re willing to make two 4-snakes. Make an S-shape, like the Tetris piece, with the head facing to the right. Make your other snake push the S-shape off the ledge, and use them as a platform to easily get the grapes and still let both snakes live.
But getting the orange is impossible with two 4-snakes. There’s nothing that lets both snakes get up there. Someone else commented that you’re supposed to make sure that only one snake eats all the fruit… Which might make sense, if it wasn’t seemingly impossible to get the grapes that way.
