Retro Arcade game goals

How can I make a level in the Retro Arcade Game creator that must be finished if you collect a certain amount of items and/or defeating a certain number of enemies?

Answer
Good question! You can use barriers, and link enemies, switches, etc. to barriers in order to prevent your player from moving on until a task is complete. You can use link logic to combine multiple objects into one switch value for a barrier, or use several barriers in progression to build a more complex goal.
