After playing this game for a bit, it's actually better than most pay-to-win energy games. It's still far from being a good game, but it's not the worst.
Why does this game even exist? It's barely more than a reskin of one of the developer's other games, and that game was awful in the first place. Clicking a button until you're told you need to either pay or wait in order to click more is not gameplay.
