- 01Released v1.1.1 in browser
- 02178 checks, zero failures
- 03Nine automated runs completed
Problem & goal
The goal was to combine immediately understandable controls with a build system worth replaying. Every choice needed visible feedback through the pet, progression, mutations, and the entire interface.
Technical challenge
The main challenge was keeping item order, recipes, DNA, dependency, and risk readable on a 390px-wide screen while supporting saves, touch and keyboard input, PWA installation, and restoration after interruption.
Solution
A data-driven core separates calculations from presentation. Previews expose growth and risk before confirmation, while pet reactions, speech, hit-stop, and score motion form one feedback chain leading to a three-stage dragon transformation.
Result & learning
The released browser version includes 17 items, 18 recipes, 24 DNA traits, 12 organs, and four endings. It passed 178 logic/save checks and nine automated UI runs without freezes.
