How long or how often you play the game does not matter, it is the time and effort that went into building the game, It takes a lot of of coding and sometimes a lot of money to make a game if you want proof of how much it costs, then go onto the unity asset store look around most of the assets are not free  not saying the developer of this game uses unity but that can be a reference, also cost of development can be even higher if you don't do the artwork yourself . Some people make games as a hobby and sell them for some spending money and other people make games for a living. complaining about spending money on a game is like complaining about spending money on a piece of Jewlery you don't need it but it still takes time and money to make there are loads of free games on itch don't complain because the developer value's their work. If you want a game suggestion, there is lust doll or lust doll plus they are both free.
