Hello.
Thanks for your kind words.
I was thinking of showing how many demons you own and how much auto income you have - but it didn't really fit into the screen. It was simply too much.
A feedback for button click is indeed a very good idea, thank you for that advice. And also thanks for the free resoruces link, I can definitely use some of them :D I couldn't find any free assets in the unity store, that would satisfy me.
I hope you had some fun with the game and could complete it :-)
