Open the editor at /app. You'll see an empty state with three options:
- **Start with a template** picks one of five small animations to remix. - **Import image** drops a PNG/JPG/GIF and pixelizes it into a starting frame. - **Start from scratch** opens a blank canvas at your default size (64×64).
Pick a template to feel the editor first. The pencil draws single pixels. Press B for pencil, E for eraser, G for fill bucket. Add a frame with the + tile in the timeline, draw a tiny variation, hit Play.
That's the loop. Everything else builds on it.
