Arrow keys to move. T to talk. You will see the rest in the top right. Red means only your top half can enter. Orange means only your bottom half can enter.

Yellow means that only your bottom half/full body can enter. Grey means that only your top half/full body can enter. You can suggest level ideas in the comments!
Your top half can't jump, but can pick up boxes. Your bottom half can jump, but it can't pick up boxes, but it can push blue boxes! Your full body can jump and pickup boxes. If your top half has picked up a box, it will hold it over its head. Then your bottom half can jump on the box that the top half is holding for extra height, or just to hitch a ride!
