This is really amazing feedback, thank you so much for writing such detailed thoughts. I'm really flattered that you played the game enough times to see all the dialogue! I had a lot of fun writing, animating, and generally trying to capture a silly upbeat feel so I'm glad it translated in the final product.
As far as your specific points:
(1) This is a really great point that I had not considered at all. I was a little unhappy with how the wizard controlled generally (using arrow keys felt clunky compared with a more "twin stick" or mouse and keyboard approach) and tried to keep it as simple as possible. I think your suggestions here are spot on and would give you more flexibility while playing him.
(2) His attacks are supposed to be on a (short) timer but I kinda got that sense too that something was up while testing. I'll take another look.
(3) Hahaha, point taken. I will consider these suggestions for maximum cinematic combat : )
(4) Also great suggestions. Visual indicator for attack cooldowns specifically was on my list of improvements and I was starting to burn out so I left it out. Definitely something I will add in the next update!
Again, I really appreciate the detailed feedback and constructive criticism. I think there's still some fun to be had (a rogue-like with some progression elements for the riders / horse would be super cool), so I may keep working on this. Thanks again!!
