Is this legal? – Insect Smasher for Kids Review

First off, I have to leave a review to unlock baby mode. Stupid! Second, we had this game when it was just called Ant Smasher and we paid to unlock kids mode and paid to remove ads. Now, the game has been changed to another name and we have to pay again to remove ads and unlock kids mode. So where did my money go? It may be a cheap purchase for us who buy but it's making this company/creator more money by doing this. Imagine how many people have paid, then have this happen and they pay again really for the sake of the child who loves to play this game. The money adds up for whoever is making money off this game! I want to know if it's legal for us to pay, have the game change, we lose what we paid for and are asked to pay again? This game is fun for my toddler but I'm not going to keep paying for something that I already paid for. This game doesn't even deserve one star but unfortunately you have to give it one just to do this.
