I don't know what to do, and I know you said you made it more understandable but it still really isn't how do i destroy the crate and wall at the same time? How do I reach the medkit? I don't know.
The labels give clues on what to do, but if you want to know, first you have to jump on the tree, then you need to hit the box with the red one and then hit both with the purple one. Thanks for playing the game!
