The games

Keep Rising

Every ending, a stronger beginning.

Keep Rising is a medieval defender-incremental for PC and Steam, single-player, currently in development.

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.

The game that named the studio’s direction. It started as a jam prototype about a very stubborn gate — then the prestige loop clicked, and it refused to stay small.

Formerly announced as Castle Defender.

Botanitech

Quiet on the surface. Relentless underneath.

Botanitech is a bio-engineering garden incremental for PC and Steam Deck, playable solo or in two-player co-op, in development for 2026.

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.

And for the hours after the siege: the quieter incremental on the bench. Same love of growth curves, traded from cannons to chlorophyll.

One person behind the lantern.

I am the whole studio — design, code, art direction and the late-night bug hunts. Quantum Lantern is a one-person operation by choice: it keeps the scope honest and lets every system get the attention it deserves.

  • 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.

  • Warm loops

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

  • Slow craft

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