A single-file, browser-based tool to rapidly assess isometric tilesets and allow simple editing.
Motivation: I just wanted to check if a bunch of tilesets would tile smoothly and quickly experiment with how to cut them. It's a simple task, why should you install a 100MB+ tool to do it?
Just open it in your browser. Tested only in Chrome.
Example tileset included by: scrabbling.
The /src folder contains a tidy version of the project split into separate HTML, CSS and JS files, if anyone ever feels inclined to modify it or plans to serve it.
