I love card battling! There's definitely some better approaches to the controls that could be taken, but I think the main thing I was having issues with was the fact that I couldn't seen enemies off screen or even knew where they were oriented when they were spawned in, which made it hard to prepare and avoid incoming projectiles once other wizards starting showing up. Some indicator that something is about to come from off screen would be much welcome, or even zooming out and being able to view the entire map while playing rather than the camera cutting off sections of the play area.
Great work getting all these attack patterns and enemies to work in the time we had! Hoping to see more done with it after the jam is done :D
