Platformer Lab

A browser-based instrument for tuning, measuring and comparing platformer movement.

Platformer Lab experimental interface with movement controls, a room viewport and jump measurements
Experimental redesigned shell, September 2026. This interface has not yet replaced the original working lab.

Overview

What this project explores

Platformer movement is often tuned by repeatedly playing and adjusting code. This lab creates a dedicated space to change parameters, replay the same inputs and compare outcomes. It is a design tool rather than a standalone game.

Contribution

My role

Specification, experiment design, acceptance criteria, milestone decisions and manual testing. AI agents implemented the code through a builder-and-reviewer process that I directed.

Current state

What exists today

  • Deterministic movement simulation, recording and replay, live tuning and A/B comparison with ghost trails.
  • A room editor, movement presets and measurement exports support repeatable experiments.
  • Physics presets are checked against the existing Kfotzumhots prototype.
  • The working lab and the experimental redesigned shell are separate versions. The docking interface shown here belongs to the improvement experiment.
  • Usability and visual presentation are still being refined; no public demo is currently available.

Where it goes from here

Continue the redesigned shell, including variant controls, and improve the workflow for creating and comparing movement experiments.
