The idea of the game is cool, you know there is something in it, I would advise you to add more buildings and some quest NPCs, but not just ordinary NPCs, but with meaning (so that they show the usual controls, for example: you go to the NPCs or click on the window, a window pops up with an inscription and there is a story about the controls, because when I entered the game I did not immediately understand the controls, And also add something like a slider to the rewards, I'm also a little confused there, thank you very much in advance, I am very glad to you and your game.
P.S. Tell us more about your game on the Valve platform
