I would consider this game to be more of an autobattler/roguelite than an incremental/idler. It can be finished in approximately 3 hours. It's one of those games that feels interesting and polished for the first hour and then you realize you're just doing the same thing over and over with nothing new happening. If you level your characters and spend arena coins occasionally instead of just spamming more and more enemies to try and make the slow process go faster, there's sadly no challenging aspect. There was a beta available on itch.io released 125 days ago that was removed an hour ago, most likely due to feedback comparing the lack of additional content added. If the price was lower or if there was a demo available, I would say try it out for yourself, but at the moment I don't recommend buying it.
