Some levels have limited moves. Often, larger acorns are there which award extra moves to enable a level to be completed. Teleports move you to another location. If there are multiple teleports, they have the same destination. There are two monster types.
Skwerl monsters track the player and kill on contact.
To leave the level you must kill the monster with an arrow or by turning another skwerl against it. Smaller green monsters can be guided to a cage and turn into acorns that you must collect. They also kill on contact but do not track the player. Monsters move once for every move you make. If you want to stand still, press the spacebar to let them move.
