Great start to the game! I'll go through the list of questions you posted on Discord..
I played as the Spellbalde
Frequency of enemy attacks:
Frequency itself was not bad, but the enemies are not quick to react. So for the smaller enemies I would kill them before they had a chance to react even once. For the larger enemy the hits were pretty weak, so I could almost just tank the hits with no real concern. The knockdown was a nice touch though.
Ability to react to enemy attacks:
Overall this fell pretty good. It took me a good amount of time to master the parry/block. But getting hit always felt like my fault. I would not be against more expressive attack animations on the enemies though.
Responsiveness of enemies:
I mentioned this a little above, but the enemies aggression and movement speed were a little slow, so I could back out of a fight to regain stamina or avoid hits easily, or just charge in and overwhelm smaller enemies
VFX on hit/blocked hit
I didn't notice much in the way of vfx. Health bar was responsive though.
Stamina cost of attacks.
Stamina cost felt good. I got a good number of attacks in before having to let my stamina regen.
Camera positioning
Camera positioning was fine, but something I wanted to put in somewhere is the mouse sensitivity. MY camera was wildly flying around with even the slightest mouse input. An option to control this would be very appreciated.
