Went on a bit of a break from UL to grind those behemoth stones, and boy was I ready to test out my new guns. Awakened Naala basically crushes this first Luza stage, and absolutely demolishes Luza as well as the Loris.
The startoff is pretty simple, since Haniwanwans' high hp and single target attacks makes them super easy to stall. The Ragin' Gory can be taken care of with Pizza and some meatshields. Once your money is close to max, you can start stacking some Couriers on the Haniwanwans so you can get in tons of damage once you hit the base. Spawn Doron once your stack is close to the base so he can land a hit on the base enemies.
Once you hit the base, it's honestly pretty much a matter of spamming and keeping Awakened Naala alive as long as possible. Focus more on Can Can and Courier at this point since they're faster and more likely to land hits. You should be able to beat the stage in two Naala spawns.
