Maybe a way to go back between early worlds instead of having to complete it as you might not be able to get any more resources so you wouldnt be able to get resources that you need and cant get more of
IF I CLICK ON THE GAME WHILE IT SAYS LOADING RESOURCES IT AFTER A WHILE IT SAYS IT CRASHED IN A LITTLE TAB WHERE THERE ARE 2 OPTIONS OF KILL NOW OR WAIT AND IT KEEPS COMING BACK UP UNTIL I PRESS X IN THE CORNER
each level has all the resources needed to complete it.
