Hey there!
Thanks a lot for your feedback, and I’m sorry you had trouble adding this asset to your Unity project. That’s mostly because I don’t actually use Unity myself — I work with a different game engine that’s quite different from the popular ones (Unity, Unreal, and Godot). So I didn’t really have the chance to test and fix the possible bugs or issues that might show up in those engines.
Again, thanks for the feedback, and I hope you still enjoyed the assets!
Cheers :)
