Although there's only one gate to protect, the level is surprisingly difficult. As soon as you start a round you'll find Fiends coming at you from multiple directions that coming from all over the place so You feel like they're ganging up on you. Of course any ordinary tower won't suffice and the level requires solid tactics and heavy towers.
Personally, I decided to change my playstyle and brought in a really cool tower called Jack Joke. It made a huge difference for me. This tower delivers heavy hits and quickly destroys enemies. I placed it in the areas most populated by Fiends, and it effectively stopped them in their tracks without taking much time. Every time an enemy approaches, Jack Joke descends, knocking them back before they even get close to the gate.
But honestly, Jack Joke alone isn't enough. You also need something that can hit quickly and cover multiple areas simultaneously. This is where the Gloom Owl tower comes in. This tower feels like a mysterious bird, but its strikes are extremely fast and annoying to the Fiends, helping you quickly cut down a large number of them before they reach any dangerous point. I used it near the side paths from which enemies suddenly spawn, and it really helped me control the situation more.
This combination of Jack Joke's heavy strikes and Gloom Owl's speed was the solution that got me through this level after many failed attempts. You must be quick with your reactions and place the towers in smart places, as this level tests your ability to plan.
If you haven't reached this level yet, prepare well. And if you do, don't underestimate it, as it's truly one of the most difficult levels at the beginning of the game.
