I've given it a shot, and here's my thoughts and bugs I've noticed, in no particular order:
-Closing the combat/dialogue window by pressing the map toggle does not seem very intuitive to me. I feel there should be a closing button for it within the window.
-The portrait holders are not cropping too nicely for me. The faces get cut off and leave me staring at torsos for the default GothWolf graphics.
-In the first wilderness screen, the return to town is hidden behind a tree at default rotation. This can make it confusing to some players and seem as though there's no going back past that point.
-There's nothing to loot off the first enemies, making it initially unclear how to make money at all, or whether I'm missing some mechanic to gain loot. This only clears up once the player fights the first enemies that do have loot, and only if the player notices the buttons by the enemy names.
-Some of the grass appears as completely black in the 3d scenes. This is without shadows enabled.
-I've had razzyberry bushes appear as unpicked while being unclickable, despite having been picked before. I'm uncertain why this happened in that particular case (I could not recreate this with other bushes), but it was around the starting area, after returning to and from town.
-The exit out of Chad's gym says "down" rather than "town".
-The "South" label within the chamber with Gareus and Belmont is located atop the entire room rather than at the appropriate exit.
-I got some skills out of Chad's gym, but do not appear to be able to use them in combat.
-Being unable to see the door from the other side of the wall in certain scenes seems a bit odd.
-The combat could use some hotkeys or even autoattacks given most rounds just end with me punching things or reusing the same abilities as long as I have the AP.
-The combat messages for fails seem a bit vague at the moment, though I assume they're placeholders.
-Personal preference, but fighting non-humanoid enemies, particularly in a sex game where a lot of the content is going to be based around humanoid-humanoid interactions, is not that interesting to me.

That's exactly what I was looking for, I'll try to reproduce and fix what I can!

Just a heads up (I'll be putting these in a help menu and dialog at start).

- You can click and drag to look around on the map, and use the mousewheel to zoom
- The combat UI can be toggled by hitting space
