Thanks so much for the great feedback! The aiming I entirely understand. The problem with rotating it all the way was that the animation didn't look good that way; earlier there was an aimer UI element that showed where you were aiming, but I removed that as I thought it wasn't necessary. Good to know that it may have been useful though.
Your thoughts on the pacing are great. I was worried about people being able to skip through too fast, but the slow mana regeneration might just feel like punishment. Definitely good to look at again.
It means a lot that you enjoyed it! Thanks again!
