It's pretty frustrating how time-gated 90% of this game is, upgrading even just one character, progressing through the story, leveling, etc. Under the progression system is a solid rail-shooter with great visuals, music, and gameplay. I guess my main complaint is the story should be easy for casuals to get through, but even after literal dozens of hours I'm barely halfway through the chapters that came out after launch.
If the story wasn't interesting I would not be playing anymore, but even then my patience is tested when 95% of fights are waves of trash mobs. You spend most of the time fighting pointless waves of enemies between each cutscene, separating them by multiple minutes at a time. The often poor translations sometimes makes dialogue feel disjointed and nonsensical.
It has "potential" and I can see this game improving a lot in the near future, but there are too many small issues that add up.
