← v0.1 Overview

Size & basics

The player is a 32×32 px square (1 grid cell). They spawn at the spawn point at game start and respawn there (or at the last-touched checkpoint) on death.

Movement

• Horizontal speed — set by playerSpeed in map config (default 5).
• Max fall speed — capped proportionally to gravity so the player doesn't rocket off-screen on high-gravity maps.

Jump

Default: 1 jump. Configurable via maxJumps. Jump height is controlled by jumpForce (default −13.2).

• Infinite Jumps — the player can jump anytime, unlimited.
• Additional Air Jump — grants one bonus jump if the player walks off an edge without jumping (coyote jump).

Gravity

Default 0.71 per frame, configurable in map config. Higher values = faster fall; lower = floatier.

Physics touchboxes

• Ground touchbox — x:0, y:8, w:32, h:24 — for solid collision.
• Hurt touchbox — x:4, y:6, w:24, h:24 — for spike damage detection.

Death & respawn

Death occurs when the player's hurt touchbox contacts a lethal spike, or when the player falls below the map's die line Y (default 1000). On death, the player respawns at:

1. The last activated checkpoint (new in v0.1), or
2. The spawn point if no checkpoint has been touched.

Checkpoint interaction

When the player touches a checkpoint, it becomes their respawn point. The checkpoint changes color to indicate its state (see Checkpoint). In v0.1, checkpoints do not heal HP — they are purely respawn markers.
