Grow a living defence from trees that combine, mutate, and respond to an advancing industrial threat.
Unfelled is a native iPhone game about spatial choices and interacting systems. Six tree species produce fifteen graft and mutation reactions across a ten-map campaign.

Dragging a Dogwood card collapses the tray so the forest stays readable during the choice.
The forest is the interface.
The player should be able to see where a choice can land, what it will combine with, and what changed after the reaction.
Choice on the board
Cards and essence are spatial decisions. Dragging through the forest reveals valid targets and keeps the battlefield visible while a choice is being made.
Hybrids that read as hybrids
Combined species need mechanical identity and visible character, so mutation work spans rules, effects, tree presentation, and the explanation shown to the player.
Versioned domain rules
Combat, reactions, and campaign behavior are modeled so a saved seed can be replayed against a known ruleset instead of drifting with presentation code.
A hybrid, inspected
A reaction has to be legible as a system, not just an effect.
This Maple–Dogwood inspection keeps parent species, health, targeting behavior, and the resulting abilities close to the tree. The goal is to make discovery understandable without flattening it into a spreadsheet.
An in-development view of the hybrid inspection system.
A living system that can be inspected and tuned.
Repeatable game logic makes the system easier to compare while play sessions keep the design grounded in the choices people actually make.
01Seeded simulations make changes to rules, pacing, and campaign conditions easier to compare.
02Automated runs can reveal balance patterns and unusual interactions across the living system.
03Play sessions answer the different question: whether each choice reads clearly and feels worth making again.
