You expect us to grind to 10k coins with just the ball and gun turret? Yeah no thanks im gone. A game needs a lot more than just one enemy and one tower.
You will unlock Rebirth pretty fast, and it allows you to increase max count of the turrets, and also to significantly increase income, so 10k wont be a problem.
Waaaay too slow, even for an idle game. Within only 10 minutes im already tabbing over to other things to let resources accumulate. Awesome game, but please speed it up a little.
Yeah, Im planning to do such an option
