Not quite. You move around, aim your moves, etc. You don't use towers, you play as the Pokemon and last as long as possible.
You can move around pretty quickly with Agility, push enemies away from you with Whirlwind, dish out big damage with Hydro Pump, put enemies to sleep with Sleep Powder, etc. Use your moves to survive and kill enemies.
I put a demo video up on the link so you can check it out before you download
