I like this kind of game. But as you said is unbalanced for now and I want to spam those create troops button. I hope you will make updates !
Maybe you can be interested by this project I participated to develop https://github.com/rakugoteam/Rakugo-Game-Template. It handle a pause menu when you press escape, and you can quit the game too :)
