I don't see a skill tree really being necessary, because in the game we can buy skills and learn stats from books or scenarios, so a skill tree seems a bit off.
Ik but would be better if you could use skill points instead of money to unlock skills and more skills would be great too like idk maybe more stamina regeneration while running also losing stamina in fighting would balance this bc in late game running becomes useless
Well, in the late game, everything becomes useless, because you FINISHED the game. And I think the dev wouldn't like to work on changing the entire shop system just to add a skill tree.
