What it is
A level-based card puzzle. Each level gives you a fixed set of cards and a recipe table. You lay the cards out as a stack; once it runs, every step applies the recipes as local matches and replacements, and the goal is to push the stack past the height limit. There are five chapters and 50 levels. The game is built with Godot 4.7 and C#. The interface is drawn in code and the sound is synthesized at runtime, so the game ships without audio files.
Responsibilities
Level, interface and interaction design and development, plus making and distributing the promotional material. Also built a web-based level lab for trying mechanics before building them in Godot: a level can be put together quickly and its solutions worked out.
How the team worked
Two people and two coding agents, Codex and DeepSeek, took turns on one machine. Everyone used the same AGENTS.md and the same skills. Before switching, whoever was working committed their changes, stopped the game instance they had started and handed over what they had verified.
