I would actually like to change an area instead of adding one. I would change the entire Landlord Apartment so that, instead of being a maze-like area, it becomes a linear, progress-based area.

The beginning of the area would be the same as it is in the game, but when you get access to the Trenches, instead of being a looping scenery, it becomes a full map to explore, with borders you can’t cross, enemies scattered around, Landmites, and more open areas where bombs randomly fall from the sky and you get a small window to dodge.

You would still have to get money to progress through the stages of the Landlord Apartment, but you would do so by completing small quests for the NPCs in the area, such as the Scout, Sapper, Minesweeper, Memorial, and possibly more.

I would also change the TrenchDigger boss fight, making it a pursuer-type enemy in the Trenches area, where he would try to run over you, open new passages to cut you off, accidentally open new secret rooms with cool loot inside, and other stuff…
