Thanks for the well-written review, Leonard!
You are right; there should be something to spend the money you earn, as there is no point in working if there is nothing to buy with it. During development, I had the idea that the player could buy a house and start a family, but due to poor planning, I didn't have the time to add it.
Regarding what you mentioned about abilities, that's an interesting idea. I will work on it. Thanks again!
