Lovely, lengthy campaign with small issues. 4/5 stars.

Back to School is a classic for a reason. The environments are breathtaking and varied, and your progression is expertly paced. The worldbuilding is also surprisingly engaging despite the iffy English translation. Back to School is 2 or 3 times as long as a vanilla campaign, but that's no issue when the quality is so high.

However, it does have problems. I had missing NPC audio and missing building textures even though I subscribed to every part.

I'm also conflicted about the final chapter in the titular school. In terms of raw design, it's the standout chapter in an already standout campaign. But exploring the school is less fun than it should be because it's full of water AND it seriously lacks health items. Pick one! These two things combine to make it a slog, and then the finale fight afterwards is way too easy. I guess I'm glad I didn't die and have to retrace my steps...

Still, this campaign is a must-play overall!
