Thanks so much!
"The mouse movement took some time to get used to, It was a bit strange on how it was rotation based?"
It's based on the X-axis of the mouse movement, I was attempting to go for something that felt like a Twin-Stick-Shooter type of aiming but was having issues with getting the Y-axis working correctly using Unity's new input system.
"I would have loved to see a block or such, or a visual indicator that I got hit. Definitely needed a health bar!"
A great suggestion! Some kind of animation similar to enemies getting hit would be a great change. There should be a health bar at the top right corner of the screen above the EXP, Wave, and Skill Point bars :).
