The collection / 01—02

Two worlds.
One restless imagination.

A fortress that remembers.
A garden that never stops.
Something worth coming back to.

Defender-incremental

Keep Rising

Fall. Rebuild. Rise higher.

↘

Hold the wall. Grow the numbers.

Every ending.
A stronger beginning.

A medieval defender-incremental. Actively command towers, troops, heroes and spells to hold a castle under endless siege — and when the walls finally give, prestige. Your fortress persists between runs, growing from a wooden keep into a god-tier citadel: every siege you lose makes the next one winnable, and the numbers never stop climbing.

Garden incremental

Botanitech

From one small sprout. To something extraordinary.

↘

Cultivate the machine. Compound the wild.

Quiet on the surface.
Relentless underneath.

A garden that compounds. Aboard a drifting orbital arboretum you splice circuitry into seedlings, and every specimen you get working feeds the next: more light, more power, more garden. What starts as one glowing sprout slowly snowballs into a whole humming ecosystem — quiet on the surface, relentless underneath.

Quantum Lantern Studios lantern logoThe light stays on.

Small studio. Long horizons.

Made by one.
Built to mean something.

I'm Florian. Designer, developer, and the person who keeps the lantern lit. I make worlds where every stone you lay and every seed you plant leaves something behind.

Games for the quiet hours. Deep systems, warm worlds, and progress you can keep.

Progress you can keep

Every session should end with something permanently gained — a taller keep, a brighter bloom, a number that will never be that small again.

02 /

Warm loops

Incremental does not have to mean cold spreadsheets. The math wears a world: lantern-light around the numbers, never instead of them.

03 /

Slow craft

I would rather ship one small world that truly compounds than ten that merely flicker.

Behind the glass

Work in the making.

Notes from the studio
01
Keep Rising / Jun 2026

Why a cosy studio went incremental

It was supposed to be a weekend jam about holding one gate. Then the prestige loop clicked and nobody slept.

02
Botanitech / Apr 2026

Wiring the first seedling

How the splice system turns a humble sprout into a living circuit — and why we rebuilt it three times.

03
Studio / Feb 2026

Notes from a solo campfire

One indie dev, one stubborn lantern, and the rituals that keep the light on.

Tech / Jan 2026

Lighting the greenhouse

The soft volumetric glow that gives our nights their warmth, without melting your GPU.

A little more light

Curious?

A few things you might be wondering.

What is Quantum Lantern Studios?

Quantum Lantern Studios is a one-person independent game studio founded by Florian Fülbert, making warm, curious incremental games — small worlds where the numbers keep growing. The studio is currently developing two titles: Keep Rising and Botanitech.

What is Keep Rising?

Keep Rising is a medieval defender-incremental for PC and Steam, currently in development. You actively command towers, troops, heroes and spells to hold a castle under endless siege, and prestige when the walls finally give — your fortress persists and grows between runs. It was previously announced under the working title Castle Defender.

What is Botanitech?

Botanitech is a bio-engineering garden incremental set aboard a drifting orbital arboretum, in development for 2026. You splice circuitry into seedlings and every working specimen feeds the next, compounding one glowing sprout into a whole humming ecosystem.

What platforms will Botanitech release on?

Botanitech is planned for PC and Steam Deck. It can be played solo or in two-player co-op.

Who makes Quantum Lantern Studios games?

Every Quantum Lantern game is made by Florian Fülbert, the studio’s founder and sole developer, who handles design, code and art direction. You can reach the studio at [email protected].

When will Quantum Lantern games be released?

Botanitech is in active development targeting 2026. Keep Rising is also in development and does not have a release window yet. Release news goes out through the studio devlog and mailing list first.
