Software with Tilemaps

Aseprite is a pixel art editor built around sprite work: an indexed-color workflow, onion skinning and a timeline for animation, tilemap layers, custom brushes, and export straight to sprite sheets. Extensions and Lua scripts add anything it lacks. It is the editor most Lospec artists reach for first.

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.

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.

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

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.

Pixel Studio is a pixel art editor that runs on desktop, phone and tablet with the same project open on all of them. It covers layers, animation with onion skinning, tilesets and palettes, and reads and writes Aseprite files, which makes it a practical way to keep drawing away from a desk.

Tiled is a flexible tilemap editor supporting orthogonal, isometric and hexagonal maps, with importers for most engines.

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.
