Very cool design. But unfortunately I don't like clickers. Also, I don't have access to my personal computer. I play on a 2008 laptop... Unfortunately, the browser starts to slow down very much while loading the game. Have you used unity?
I'm very sorry to hear that, nope we used Godot, exported file is like 5 MB. Only thing I've noticed is the game seems to freeze for a frac of a sec after the very first mining.
