Be proud of your game!
I don't know if there is really a place to go after getting all of the items, but it's a cool experience, especially visually.
I liked also that the doors are breakable, and that after killing an NPC, the others would start running (and sometimes they're quite hard to catch!).
At twitter you should have posted that you launched the game, I saw your latest post and thought (oh, another screenshot of the game) but I didn't notice you posted the game until I opened my itch.
