Dev here!
Combat feedback is really good because I rarely get that from players. I will try to explain why combat is the way it is. When I was designing, I had two basic choices for structuring it, one of which was low accuracy, high damage, low health, the other being high health, low damage, high accuracy. I sided for the one that was less of a battle of attrition because I thought it would feel better for players to one-shot an enemy rather than have to whittle them down. I understand that the combat still needs work though and it's on my todo list.
I will say that one of the main ways I tried to discourage players from going where they weren't experienced/equipped enough for yet was with monsters that were basically impossible to hit because of the disparity between your dodge chance and their accuracy. If you're butting your head against really hard monsters that seem impossible to beat, there's a chance you're actually not supposed to be there yet.
That being said, I want to make this game as good as possible, even where combat is concerned and I'm not above very large overhauls. I have taken down your feedback, but if you have any concrete suggestions for how I could make the combat feel better for you, I'd love to hear them!
Thanks for playing!
