08 / Botanical genetics & tower defense
Zero Reagent

Turning inheritance rules into a playable system. The current game, MUTABLOOM, connects gene combinations, botanical evolution, and tower-defense decisions in an expedition.

01 / The challenge
Make combinations and randomness worth exploring while keeping rules probabilities and trade-offs legible to the player
02 / Approach
- Make randomness explainable and rules testable
- Separate inheritance and combat models from rendering and interaction
- Support deliberate decisions with probability previews, state feedback, and focus-loss pause
03 / System structure
- Inheritance: gene slots, expressed traits, hybridization, and mutation
- Rules: combat model, event queue, and expedition settlement
- Experience: Phaser scenes, laboratory, and discovery catalog
- Storage: browser-local preferences, discoveries, and unlocks

04 / Public outcomes
What the work established
- A desktop-browser single-player prototype with an actual interface
- A plant-building loop spanning hybridization, evolution, and mutation
- Reproducible randomness in a rules layer separate from visual presentation
