Hi Tyler, first of all thanks for the feedback.
Documentation is something we've been working hard on over the last couple of months. Very soon a full set of Docs will be available on the website, breaking down how every feature works. I will look into getting some specific tutorials added to this page on creating certain sprites e.g. tiles, trees, humanoids etc.
We will also be uploading another Introduction Tutorial on YouTube, which includes all the features added in updates since the first video.
The demo version was originally restricted to creating 1-bit sprites, however is now fully functional with every feature except export. We also have 15 example grids you can load from the software Welcome Screen to get you started quickly.
