Terrible performance! Eats through battery faster than Rimuru through a Hipokute herb field, even with graphics turned all the way down. Slowdowns as the game runs, eventually crashing. Startup is very slow. Lots of unnecessary section reloads. Sounds even when muted. Terrible color contrast and font sizes. Starting gameplay is a fast slog, but then you hit a level and gear wall and gameplay becomes significantly slower. Finally, it is a ridiculously prohibitive gacha.
