# Platformer

A playbook for 2D platformers — the run/jump controller "feel", level structure, hazards,
and goals. This is a **compositional** skill: it wires an engine movement skill, a tilemap
skill, and design skills into a working game. It does **not** re-teach physics or tilemaps;
it tells you what to build and how to make jumping feel good.

## When to use

- Use when building a side-scrolling or single-screen platformer, a "Mario-like" /
  "Celeste-like", or any game whose core verb is **jump between surfaces**.
- Use when a jump feels floaty, unresponsive, or "unfair" and you need feel fixes
  (coyote time, jump buffering, variable height, corner correction).
