All of our levels are designed to be beatable without the use of any premium items such as Lemming Resurrects or boosters. Since the Instructions Unleashed update, some levels on later planets may require the use of Advanced instructions (such as rockets, gliders etc.) in addition to the basic instructions. If you wish to know how to switch your instruction set, you can find a guide here: How Do I Change My Instructions?

If you encounter a level that does not seem manageable without premium items, feel free to reach out to us via the Support button in the Settings menu of the game so that we can assist you.
