Making a Retro-Style Game with PICO-8
Making a retro-style game with PICO-8 fantasy console. Covers Lua scripting basics, using the built-in sprite and map editors, composing chiptune music with the tracker, and publishing to itch.io or the PICO-8 BBS.
128x 128 px
16Colors
Setup and First Script
Purchase PICO-8 from Lexaloffle. Launch and type EDIT to enter the code editor. Write a simple _update and _draw loop. Print something to the screen. Run with CTRL-R. The constraint of a single file encourages focus.
Sprite and Map Editors
Open the sprite editor with CTRL-G. Draw 8x8 pixel sprites using the 16-color palette. Assign sprites to map tiles in the map editor. Use mget and mset in code to read and manipulate the map at runtime.
Publishing the Game
Export to a PNG cartridge with EXPORT cartname.p8.png. Upload to the PICO-8 BBS for community visibility. Export to HTML with EXPORT cartname.html and upload to itch.io as a web playable.

The PICO-8 token limit (8192 tokens) is the primary constraint you will hit in larger projects. Optimize code by using single-letter variable names, combining functions, and removing debug code before publishing.
