First of all, thanks a lot for the huge write up! It’s really valuable feedback. This is my first game and I'm still studying so I did not expect people to like it this much haha! The dash cooldown defo could’ve been presented better with an animation, I agree.
Also, in case you want to get further, another bug I didn’t get to fix is: If you time it right, you can not take damage from the big knight's sword by being in the middle of an attack such as a stab, only works if you've killed something with a previous attack and then are stabbing the corpse.
