Thank you for playing my game! Sorry for taking so long to reply.
Those are good points you bring up, I will fix them.
I'm hoping to have graphics by the next demo day, and if I can't do it, then at least an item system in the combat prototype, for health recovery items and the like.
Although the characters are not well defined since I don't have a defined story yet, I do have some ideas of what they're like and when more system implemented we may get to know the characters together.
By the way I love the treasure chest backpack the character has in your game.
I will merge it with this other project I have and it will look like this but more finished in the future.
