Battle, by 
I would not have guessed this is a Dragusela level. Honestly I would not have guessed this is a 2024 level! It's so… indoors! It's almost a single tileset despite using four separate .j2t files, but it's all visually coherent. (The giant porthole is a bad resizing job though.) It's got really solid, intricate use of layer 4 and doesn't just lean on the background layers to sell itself. Battleship is not a tileset that I find easy to make look this good, so, kudos. I can see the Maelstrom comparison but it also reminds me of Dethroned, interestingly enough…
My biggest issue is the level is just a bit bigger than it needs to be. I think you could cut out about a fifth of its width, some of the area between the seeker and toaster powerups, and be fine. The far right area with the wide springs is also quite expansive but like, it's showing off, it's cute, it's fine. Check out all these springs! The sucker tubes into the top powerups are super campy but, well, I guess you know exactly what you're letting yourself in for, right?
This is a level I respect a lot but have never quite fallen in love with. It's not quite got a central concept that I can gel with, although it does do interesting things with vertical space. But it has lots of great bits scattered around, and again, the detail work in the walls is a treat.
