Build a small, playable browser game inspired by "Leechside Manor" (genre not listed).
Concept: Paris, 1828–1832. Dr. Broussais orders thirty leeches for every patient, France buys them by the tens of millions, and you are his house physician at the Val-de-Grâce Hospital. Place leeches on the patients to bleed them. The leeches will fall off when full but the soldiers….
Tech: use plain HTML, CSS and JavaScript (or a lightweight engine you know); keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): WASD to move, Esc/P to pause. Show them on a short how-to-play screen.
Players: start single-player (the original's player count is not stated in its listing).
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.

The engine Leechside Manor was made with is not stated in the source. Its listing mentions Claude as an AI tool used to make it.
How do you control Leechside Manor?
The game's own page mentions arrow keys, WASD and Space. We detected this from the page text; the creator hasn't confirmed a controls list.
Does Leechside Manor work on phones?
Probably not well. We could not confirm touch controls, so a keyboard or mouse may be needed.
Is Leechside Manor multiplayer?
Not stated in the source.
Where can I play Leechside Manor?
In your web browser on ldjam.com, linked from its listing. Vibe1Up links to it and doesn't host the game.
Is the prompt for Leechside Manor official?
No. The prompt on this page is a Starter recipe: our own reconstruction from the game's public listing, not the creator's official prompt. If you made this game, you can share your real prompt at vibe1up.com/prompts/ and we'll show it with the Creator's prompt badge.
