DHSeaDev — the complete index

GAMES

Every game DHSeaDev has made, and where you can actually play it. Some run in any browser with nothing installed. Some are Chrome extensions. This page is the memory bank — one place that remembers where each one lives, so you never have to go hunting through the projects index for a link you half remember.

Everything here is free and runs on your own machine. No accounts, no trackers, no ads, on any of it.

Play right now — the arcade

Seven games at play.dhseadev.online, each one a Chrome extension rebuilt to run as an ordinary web page. Nothing to install, nothing to sign up for. Progress saves in your own browser.

Prism Cascade

Charge, shatter, splash. A hundred levels of physics arcade, thirty seconds at a time.

Lumenreel · Prism Crash

A slot machine where the only thing you can stake is time. Lumens accrue at one per second whether the tab is open or not. 125 critters to find.

Underglory

A hundred hand-drawn mazes. You never move the plant directly — you lead a morning glory up to the arch and hope it follows.

VEILFALL

Nine souls hold a ward, and one of them came through the Gate wrong. Solo hidden-role deduction with nobody to lie to but yourself.

Emberkeep

Carry the light through the keep. A puzzle platformer about a fire spirit and the things that go out when you stop paying attention.

Emberkeep — Mountain

The isometric ascent, and a mountain whose geometry does not entirely agree with itself. Light it anyway.

Bloom Rush

Propagation Station. Pot, water and ship the orders before the bell, in the tradition of every restaurant game that ever ruined an afternoon.

The Appraiser’s Loop

An isekai RPG where nothing has a number until you look at it. Appraise monsters to make them readable, fill a Codex that survives your own death, and step back through the Veil when the run is spent.

Play right now — on this site

Two games that live here rather than in the arcade, for historical reasons that made sense at the time.

Singularity Tower Live

Seven floors, each converting the output of the one below into something rarer. Generators, workers, a tech tree, prestige relics and six arcade minigames. The complete game, in your browser.

Prism Break

Asteroids, with opal prism shards. There is a shared global best and a live chat, so you are never quite playing it alone.

Chrome extensions

Games that live in a browser side panel, a popup or a new tab. Each project page carries the store link where a listing exists, and says so plainly where one does not.

Arcanum Idle

A registry-driven mage idle game — combat, runecrafting, alchemy, pets, curses and slayer contracts across fifteen monster tiers.

Cobalt Star Idle

A deep-space incremental RPG with a 3D starfield camera, orbital physics, ascension and offline progression.

Devotion

Build favour with rival gods, run jobs across four regions, fight in the Onslaught, forge equipment from monster drops, and shape the fate of Kengir.

Spellsurge

An idle wizard bullet-heaven with auto-firing spells, build-craft upgrades, evolutions and prestige runes. It fights while you browse.

Kawaii Time Garden

A category-based time tracker that never logs your browsing history, paired with a slow-building playground of critters that hatch as you navigate.

TabCritters

Every new tab generates a unique creature. 4,096 deterministic seeds, five rarity tiers, eight elemental affinities, no background script at all.

FuturaTab

Replaces the Chrome new tab with 44 collectible characters and hand-written affirmations. Zero tracking, all local.

Dino Dots

Dots and Boxes against a dinosaur that plays real chain strategy, across three difficulty tiers.

Hotdog Rush

An endless runner in which a hotdog simply wants to get where it is going. Dodge, rack up distance, beat your best.

Annoying Dino

A dino who refuses to leave you alone while you browse. Tap, feed, distract, or ignore. He does not care either way.

Steplings

A hatch-and-collect brood raised in the browser. Merged into Kawaii Time Garden and kept here as a record rather than a product.

Planet Express Lounge

Not a game exactly — an AI sitcom engine with a hidden Dark Matter layer underneath it. Chat with the crew, or let them run an episode without you.

Everything here is free and runs on your own machine. Nothing phones home, nothing wants an account, and nothing carries an ad. If a link on this page is wrong or a game has moved, that is a bug worth telling me about — contact. The full catalogue including the tools and the non-game work is on projects, and the dated record of everything is on history.
