you should totally pay as it helps the developer of the game, but i've also dealt with the same issue. theres been so many large updates that add completely new things that i havent decided which update to settle on. idk the plans on the future updates (probably on the discord but im too lazy to check 😔) im probably going to wait on the last update for the WSIS as shes my fav character before i play again. it really depends on you tbh and i dont think this game faces the risk of deletion (i hope).
