Yeah I wanted to make the game multiplayer at first but was worried on how I could make that work. As for combat I did originally have a different idea where you can get new abilities and attacks as you progress through the game but I ended up with a very large scope and had to scale it down to just 2 abilities. I do really appreciate the feedback though and will try to add some sort of multiplayer and try to make the combat feel more strategic in a later version.
Very glad you enjoyed the game and I greatly appreciate the detailed feedback.
