I couldn't get the tool to line up a 76px by 84px hex tile at all. It was way off when I used the wizard and fenaggling with offsets really didn't help. Often need a different aspect ratio than 1:1. The itch page should detail more clearly what it can and can't do to avoid disappointed buyers.

It would be extremely helpful if the tool visualized the area being set up in any way. Instead you're left with just sort of guessing where the boundaries are.

The tool is cumbersome and the documentation is pretty poor. In your video you should at least show the menu steps. The written documentation kind of helps but is also lacking much detail. In the end it just didn't lineup soooooo? Wasted time and money.
