Thanks for playing!
So checking the video, I see that I'll need a tutorial sooner than I expected hahah. The combat is indeed working, it's not all that different than a normal RPG actually. The character you were struggling with (the healer) has a specific mechanic that I may have to explain more clearly through in-game text. I'm sorry you didn't have a great time, but it was still good to see how different people navigate through the game
