I decided to change the game from paid to free, and there were no inbound purchases or advertisements in the game. I would probably change to paid after the full content of the game was officially released.
The changes to the store's pages will be completed in about seven working days, mainly for Steam's review.
Anyway, it's the first work of an individual. It should be regarded as training hands or accumulating popularity.
Because there is no sales of games, I don't think it will have any impact on customers.
