Ist ja so schön, dass dein Spiel so viele Sprachen hat, außer Deutsch Guten Abend

So far as I can tell, the only drops are gold and gems, and there's no score listed anywhere, so what do these stats do?

Can this game be played using only a mouse?

Not sure I see the point of this, since it doesn't do anything to the game. Steam needs a slider like that magically makes everything look good.
