## Description

Build a 2D platformer: run/jump control with coyote time, jump buffering, and variable jump height, wall slide and wall jump, plus tiled levels and hazards. Use for a platformer or Mario/Celeste-like, or tuning jump feel.

# 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).

**When *not* to use:** top-down movement with no gravity → use the engine movement skill
directly. 3D first-person traversal → `fps-shooter`. Grid/turn movement → `roguelike`.
For the raw kinematic body API, use `godot-2d-movement` (or your engine's controller skill).

## Core loop

**Observe a gap/hazard → commit to a jump or move → land safely (or die) → reach the next
checkpoint/goal.** A platformer lives or dies on the *moment-to-moment* feel of that single
jump, repeated thousands of times. Tighten the controller first; everything else is content.

## Must-have systems

1. **Run/jump controller**, horizontal accel/decel, gravity, jump, with the feel aids below.
2. **Solid + one-way collision**, ground, walls, and "jump-through" platforms.
3. **Level geometry**, a tilemap or hand-placed colliders; the playable space.
4. **Hazards + death/respawn**, spikes, pits, enemies; reset to the last checkpoint.
5. **Checkpoints / level goal**, progress markers and a win condition (flag, door, exit).
6. **Camera**, follows the player with a deadzone and look-ahead, clamped to level bounds.
7. **Juice**, landing dust, squash/stretch, hit-stop, sound. Cheap, huge feel payoff.

## Design knobs (make the jump feel right)
