I liked this game, not too different from other idle games, but it was simple. Too bad, as others have said, it is broken now. No point of having and idle game that only works when it is open. It also happened a few days ago. Even the skills won't decrease timer if the game is closed.
Regarding the error of the save not being found, reloading the game does work since it finds the saved game.
My feedback: The only thing I would like to see different was the "Back" button, sometimes it was almost invisible, I guess it is due to having same colors as the background. Probably chang the color of the button or letters might help. Also of course, fix the problem of the game not progressing after being closed, otherwise, it defeats its purpose of and idle game.
