Don't allow robot to jump when tiles are above it

You can make the robot object jump even when there is a tile above of it. Please try to figure out how to make sure the robot object doesn't even attempt to jump when below a tile

Hint: The animation works by checking whether up is being held, might be better to look at y velocity.
