I saw an Itch post that a moderator responded to and they said that if you buy a game and then the price increases you retain access to it and future updates without having to pay more money.
IDEALLY, once you pay you have bought the game. I'm planning on having the price go up as more levels are added. So the IDEA is you get in early you get a better price. But I'm honestly not sure how itch handles prices increases, so I'll look more into once we are closer to doing that.
