Heart of Ice

The 1994 gamebook, all 450 sections, in your pocket.

Heart of Ice cover art: a black hovercraft skims frozen dunes toward the Sphinx and pyramids, half buried in ice under a storm sky.
Cover by Mick Posen

Heart of Ice is Dave Morris's post-apocalyptic gamebook from the Virtual Reality series. The 23rd century, after the ice came back. Somewhere under it is the Heart, and everyone with a gun and a hovercraft wants it. You pick a character, turn to section 1, and start making bad decisions.

The app keeps the book intact: Russ Nicholson's illustrations, every page, every dead end. It adds what paper can't. An undo. Checkpoints. Four difficulty levels, automated dice and inventory, music, and a font size you can actually read. No ads, no microtransactions. Works on a plane.

  • 450 sections
  • 4 difficulty levels
  • Undo + checkpoints
  • Offline, no ads
  • $3.99

  • The Explorer's inventory sheet: knife, gas mask, codewords, and skills.
Cartoon key art: a young adventurer with a sword and round shield faces an angry goose on a stone bridge. Behind them, pine forest, a smoking village, and a ruined castle on a cliff.

Wyrmcourt

A tile island, a daily click quota, and an economy you can rob.

Wyrmcourt is a browser RPG in the shape of the ones that kept people coming back for twenty-five years. You get a stack of clicks a day. You spend them walking the island, fighting whatever is standing on the tile, and haggling in the market. Six attributes, round-based combat, and other players in the chat window taking bread off your stall.

The server decides everything. Your browser just draws it. Free to play, and clicks are never for sale, in any form.

  • Daily click quota
  • 6 attributes
  • Round-based combat
  • Player economy
  • Nothing to install

  • Market Lane in Wyrmcourt Town: a painted street of striped awnings and barrels, a compass rose for moving, the near country as a tile map, and the island chat.
  • Round-based combat against a bracken hare, with the fight log and the action buttons.

03 · Colony survival strategy · Steam · Coming soon

Xenobiome Command

Survey the fog. Claim the ground under it. Hold the line.

A colony sim on a fungal exoplanet where the map is alive and mostly hostile. Every region is a grid of areas. Survey them, claim them, build, and then defend what you built from the bloom. Ferals march on you. Incidents, blights, and seasons test every choice. How long does what you build last?

Seventeen handcrafted story maps, then all seventeen again as seeded scenarios with four asymmetric factions. Eighteen commanders. A hundred and twenty-seven incidents. A new daily drop. Mouse, gamepad, or touch. Plays fully offline. Premium, no microtransactions, no account.

  • 17 story maps
  • 4 factions
  • 38 structures
  • 127 incidents
  • Steam Next Fest, Oct 2026
  • iOS & Android after
Wishlist on Steam xenobiome.net
Xenobiome Command key art: an armoured colonist stands with their back to us, looking over a forest of glowing mushroom trees toward a small domed outpost.
  • The archipelago map: claimed islands lit in cyan, unsurveyed fog around them, the outpost sheet open on the right.
  • The citadel map, walls raised around a central keep, wardens marching out to meet a feral pack.
  • The fungal map, bloom pressing in from three sides, an incident card asking for a decision.
  • The oasis map at night, farms and beds clustered around water, the research tracks panel open.

Petri Dish God

Sanitizer kills 99.99% of germs. You are what's left.

Two microbe colonies, lime and magenta, blooming across a dark petri dish. One has googly eyes.
Artist's impression. Artist not yet hired.

You are the god of a petri dish. Build a microbe gene by gene, seed it on the agar, then sit back and watch the colonies bloom, eat, and fight. Between rounds you draft mutations against a rising biomass target. Eight dishes to a run. Every third one is a boss.

The dishes are not lab dishes. They are an office fridge, a gym sock, a hotel remote. A nature-documentary narrator explains all of it in the calmest voice you have ever heard. Everything has googly eyes.

Steam first, then Android and the browser. No page to wishlist yet.

  • 8 dishes per run
  • ~40 minute runs
  • Draft mutations, Balatro-style
  • Googly eyes on everything
