Programming Resources for Low-Spec Art

Bitsy is a tiny editor for making small worlds: a few rooms of 8x8 tiles, an avatar that walks around them, and short conversations with the things in them. The limits are the point - there is no scripting to speak of and two colours at a time - and a finished game is a single HTML file.

Defold is a small, free 2D engine that builds unusually light games for desktop, web, mobile and consoles from one project. It is scripted in Lua, ships as a single editor with no licence tiers, and its tilemap and sprite handling suit pixel art directly.

GB Studio makes Game Boy and Game Boy Color games with a visual scripting editor and exports ROMs that run on real hardware and on the web.

GBDK-2020 is the maintained fork of the Game Boy Development Kit: a C compiler, libraries and tools targeting the Game Boy, Game Boy Color, Game Gear and more.

GDevelop builds games out of events - conditions and actions picked from a list - rather than code, which makes it a common first engine. It handles tilemaps, 2D lighting, physics and multiplayer, exports to web, desktop and mobile, and the underlying engine is open source.

GameMaker is a 2D-first engine with a built-in sprite editor and room editor, used by many of the best known pixel art games.

Godot has a dedicated 2D renderer with pixel-snapping, nearest neighbour filtering and viewport scaling options that make low-resolution games straightforward.

LÖVE is a small, well documented Lua framework with nearest-neighbour filtering and canvases that make pixel-perfect rendering easy.

PICO-8 bundles a code editor, sprite editor, map editor, sound effect editor and tracker into one tiny virtual machine with strict limits that keep games small and finishable.

Phaser is the most used JavaScript framework for 2D games in the browser. It covers sprites, tilemaps, physics, input, audio and scene management, has a very large body of examples and tutorials behind it, and runs anywhere a browser does.

Picotron is a fantasy workstation from the makers of PICO-8: a small imaginary computer with its own desktop, file system and built-in tools - a sprite editor, a map editor, a tracker and a code editor - all inside fixed limits. It is roomier than PICO-8 and keeps the same deliberately constrained feel.

PuzzleScript is a browser engine where an entire puzzle game is a short text file: a legend of characters, a set of rewrite rules, and the levels drawn as ASCII. Games run and share as a single link, which has made it the usual home for small tile-based puzzle experiments.

TIC-80 is an open source fantasy console in the PICO-8 mould with a larger screen, several scripting languages, and built-in sprite, map, sound and music editors.

Unity is a general-purpose game engine with a well-worn 2D pipeline: a sprite editor and atlas packer, a tilemap system with rule tiles, 2D lights and shadows, and a large asset store. It is heavier than the dedicated 2D engines, and in return it goes anywhere.

raylib is a no-dependencies C library with bindings for dozens of languages, well suited to small low-resolution games.
