By far one of my favorite games on Newgrounds, especially during this online schooling sh!t. I think people like Balancegrim definitely overthink this, though he poses some good questions, for example how exactly Armor works (is it just an HP buffer or does it take less damage than your health would, and what is the chance of a hit ignoring my armor?), but overall it's a very fun game, much more well-made than most games of it's type.
I definitely agree with most of the comments on here, it's a great time-waster and definitely not an overly complex game, even if it can be a bit on the vague side. I feel like it'd be interesting if there were some boss fights with stats like yours, misschance and all. I also feel like it'd be nice if you could occasionally find items like on a real battlefield. When ancient warriors found their enemies' weapons, arrows, shields, etc. they had no problem taking them if needed.
All in all, one of the best games on NG, I'd suggest this in an instant for anyone in need of a good distraction without lowering productivity.
