Well, I think being able to recharge the stamina while moving would be nice and some sort of marker on where to head next. I found myself getting lost.
Thank you for your suggestions.
Due to time constraints and circumstances, I didn't have time to add more content to the game. Because of that, I didn't manage to add consumables like stamina and HP restoratives, or something like a mini-map with markers. But since you wrote about it, it means these are genuinely useful things worth adding.
Thanks for the feedback!
