A top-down maze chase & rescue — you're lost in a haunted castle. Dodge the mummies, grab the key, rescue your friend and escort them to the exit before the timer runs out.
The original Castle was a little Akihabara-engine maze game. This is a ground-up rebuild in dependency-free vanilla JavaScript on a plain canvas that keeps the heart of it — run through a castle, dodge the mummies, find your friend — and layers on a full arcade loop: 8 generated levels, torchlight fog, keys, power-ups, spike traps, a rescue-and-escort objective and an online leaderboard. All art is drawn procedurally (no image assets).
- 🎮 Move with WASD / arrow keys (or drag on touch). The camera follows you.
- 👻 Mummies, bats and guards chase you — one touch costs a life (you have 3).
- 🗝️ Grab the key, find and rescue your friend, then escort them to the glowing exit before time runs out.
- 💎 Collect gems for score (chain them for a combo) and ⏳ hourglasses for more time.
- ⚡ Power-ups: Freeze stops the mummies, Sprint speeds you up, Torch widens your view.
- ⚔️ Dodge spike traps, and lean on the minimap to navigate.
- 🧩 8 escalating levels — each a freshly generated maze (endlessly replayable).
- 🕯️ Torchlight / fog-of-war on the darker levels for real "lost in a castle" tension.
- 👥 Enemy variety — shambling mummies (chasers), fast bats, patrolling guards.
- 🤝 Rescue & escort — your friend follows your trail once found.
- 🏆 Online leaderboard (time + treasure + no-hit bonuses) with retro initials entry.
- 🕹️ Keyboard + touch, fully responsive.
High scores go to a shared Cloudflare leaderboard — a Worker + D1
(retroix-leaderboard) shared by all of
Dan's Retroix games and namespaced by gameId, so this game's board is its own. It
works out of the box (no account, no setup) and validates + caps scores server-side.
Blank apiUrl in js/config.js to fall back to a local
(per-browser) board.
Any client-side leaderboard can be spoofed by a determined player — it's for fun, not competition.
It's a static site — no build step:
git clone https://github.com/DanMat/Castle.git
cd Castle
python3 -m http.server 8000 # then visit http://localhost:8000| File | Responsibility |
