Thank you!
Yep, I'll be pushing an update to Unity really soon. (It just takes more work to update Unity vs. Itch.io; think like 5-10 minutes here vs. 30-60m for Unity due to all the overhead.)
A suggestion for another update would be to include 2 more sprites of the windmill (In a different state) so that it can be animated using the animated tiles in Unity, or as a standalone building (Depends on how people are using it).
Once again, truly amazing set! There are only a handful of artists like you in the asset stores! Thank you very much!
