I'm happy to announce that after a long wait, Better Rule Tiles is finally coming to the Unity Asset Store. With this release I'm hoping to reach a wider user base which will hopefully enable me to develop the tool even further.

The tool will still be available through itch.io for significantly cheaper than on the Unity Asset Store, as Itch.io takes almost no cuts from the purchases. So if you want to support the development of the package, the best way is still to purchase it on itch.io.

However if you do want to buy it on the Asset Store, there's a 2 week long launch sale to get the tool for 30% less.
