Workflow guides, sprite and animation tips, and news from the Tsubu studio — written for indie game developers.
Make a Phaser sprite sheet from scratch in a browser tab, then load it properly — this.load.spritesheet with frameWidth/frameHeight, anims.create with generateFrameNumbers, sprite.play, the JSON atlas path for packed sheets, and the pixel-art settings that differ between Phaser 3 and 4.
A fair, source-checked comparison of free pixel-art software for people who make game sprites — Piskel, Pixelorama, LibreSprite, PixiEditor, GraphicsGale and Tsubu: browser or install, animation timelines, export formats and what your game engine actually receives. Every competitor fact read off that tool's own site, docs or repository on 2 September 2026.
Make a Unity sprite sheet from scratch in a browser tab, then import it properly — Texture Type Sprite (2D and UI), Sprite Mode Multiple, a 32×32 grid slice, Point (no filter), Compression None and a Pixels Per Unit that matches your art.
A hands-on guide to making pixel art a game can actually use: pick a canvas size, hold a small palette, get the silhouette right — then refine a sprite on a real pixel grid in your browser and export it as a transparent PNG.
A hands-on guide to animating pixel art: frames, frame counts and FPS explained, then build a looping four-frame walk cycle in your browser and export it.
A hands-on guide to making a sprite sheet in your browser — draw or generate your frames, animate them on a timeline, and export a packed PNG plus a JSON atlas that drops straight into Unity, Godot, Phaser or Pixi.
Tsubu is a free, browser-based pixel art studio built for indie game developers — draw and animate sprites, generate them with AI, and export a game-ready sprite sheet that drops straight into Unity, Godot, Phaser or Pixi.
