Thanks for playing and glad you enjoyed!
We used V3.6 -.NET because it supports both C# AND web export. It was a bit annoying/awkward because it doesn't come with hex shaped tiles like Godot 4 so there had to be some trickery. It probably would be easier to use version 4 with GD script, but it doesn't feel as transferable/beneficial to my portfolio.
In the future, I might look to see how Godot 4 works with C++ and web exports so I can use the newer features and a common industry language. BUT C++ hurts my brain xD
