is it only you working on the game? And do you make money from people playing your game when its free?
Yes, it's just me working on the game. I handle all the art, coding, game design, bug fixing, and updates myself.
And no I don't earn any money from Serenitrove. It's purely a passion project for me. I do plan to keep updating it from time to time, but I can't promise constant updates since other responsibilities in my life have to come first.
