Hey man! I totally get that. In fact, I have already implemented a similar system into the next patch of Ulven. There will be a monument in the main room where you can select one health boost (very easy, easy, normal), a hardcore mode, and ways of rebinding the Parry hotkey.
I wanted to combine this QoL improvement with both new content and other improvements (for instance, I made the dash a lot more responsive and completely removed the attack cooldown, as I finally managed to fix a damage-stacking bug). So a fix is on its way, but I don't really know how I should go about it with patch 1.33 and everything. Do I continue on current patch (works fine for me) or do I try to locate a 1.32 install file?
