I played the demo and really enjoyed it!
It was both terrifying and thrilling to see the stark contrast between the protagonist’s deeply human act of trying to rescue his wife and his monstrous nature—as he wandered the forest in search of human flesh, viewing bandits as resources for healing or strengthening himself and plotting how to kill them as efficiently as possible.
I did feel that the gameplay loop relied a little too heavily on collecting upgrade materials and returning to base repeatedly, but overall, I was very satisfied with the experience.
One thing I found slightly frustrating was getting consecutive low AP rolls during combat, especially when I just wanted to explore areas with weaker enemies, such as Forest Level 1.
There were many situations where I thought, "All I need is one knife attack and one gunshot," but I couldn't do that because of the low AP rolls.
So I think it would be great if there were some way to increase the minimum possible AP roll through upgrades or a similar progression system.
Getting a permanent +1 AP bonus from eating meat would probably be too powerful. Instead, I think a weapon proficiency system, where proficiency increases based on the number of enemies defeated with a particular weapon, could work really well.
To clarify, I'm not talking about modifiers like Body, Smart, or Charm. Ideally, the d20 roll itself would change from 1–20 to 2–20, then eventually 3–20, while keeping the maximum at 20.
This could also create an interesting decision whenever players find a new weapon: should they stick with a familiar weapon they've already mastered, or switch to the new one and start building up proficiency with it?
I think this would add another satisfying layer of progression while preserving the randomness of the combat system.
Also, while it's possible to play in English, I'd prefer it if there were a Japanese version.
