dude, the game have 2 years already and still have the same content i can get the "is not their main job" in the early states but when a game have years and still its an alpha is just sad asf
As said, likely no one here is paying a dime. This game isn't very popular so the developer doesn't get much support so can only work it on so much with their real job.
You can see what a lot of support gets (and financially) and how games turn out, when games are getting support, they get bigger and better updates, more content, their games usually hit Steam and many other things.
There are a ton of games on F95 like this that get very, very, little support so they just cannot devote much time to it.
It doesn't help though when they decide to rework the game, but let's be honest here, this game needed it, and it isn't an alpha, it has a decent amount of content if you never played it. Alphas are buggy and barely playable, this game is the furthest from that...
