You have a game where your player character only gets one action per turn. Only one per turn, and then every single other enemy on screen gets to move. Moving ONE square or switching weapons counts as your one action, and will end your turn. Multi-target attacks exist, but they're weak and limited.

How do you design enemy encounters?

If you answered 'put in enemies that replicate themselves when defeated at such rates and in such numbers that you will have fully 20 of them in one room that all get to move every turn while the player sits there, watches them bobble around the room for 10-15 seconds, and then can only do one action of chip damage at the nearest 3-4 enemies before all of them bobble around again', please do not make games. But if that WAS your answer, you should play Rogue Wizards and see how much fun you have.
