I have enjoyed the anime, both film and series.
This game is a continuation/spinoff of the anime. If you forgot who is who, it does a good job of reminding you.

The Pros of the game:
-It's really easy to play, controls are easy
-I don't think there even is a Game Over screen, as if you fail, you just end up outside the dungeon
-Sound and music are good
-Translation is well done
-Nothing is missable, and eventually all the sub events will unlock by the end of the game
-Akko's Room (the ability to skip time is a blessing)
-Movement Magic (teleport to other waypoints (they are save points))
-Shop layouts help sell items sort of quick
-Ehancement/Enchantment system was not needed to beat the game and could be ignored altogether - It's found in the Lab


The Cons of the game:
-The Labyrinth seemed underutilized and unnecessary, and why is there unlockable magic there for completing it? The magic isn't even needed for the achievement. "Learn All Battle Magic" means just that, "learn", not upgrade, as in 1 point. The unlockable magic from this could have been rewards for the endings.
-Events and Sub Events do not do a good job of telling you how to about them
-Events and Sub Events sometimes take a moment or hours in-game, making planning of projected plans sometimes get delayed- This happened to me several times, whereby I would be like, "I'll do this one Sub Event and go to the next Sub Event in the next room, which will start in 10 in-game minutes". Then, it would fast forward 3 hours, missing the deadline for another Sub Event.
-Drop Rate. This was the most time consuming task and the worst part of this game. I would need a specific drop (quest item or decoration), and it would not drop. I would run the dungeon over and over, sometimes taking 30 minutes for a mushroom or quest item to drop, and hours for a decoration. I loaded up my cleared save data and was going to farm the decorations until I had them all. It took me about 9 hours to get them all. With, Canopus Ruins 4 having ran close to two dozen times alone just during this session alone. This was with over 300 in Luck and increased drop rates on each of my equipment for Akko, who had reached level 99 in the process. Not to mention, every other item would drop like crazy in the upper dungeons, leading me to have to go to a shop to sell items very often. There really should have been an option to buy the decorations in the shop, as I ended the game with over 1 million currency. This is obviously my biggest gripe about the game.
-English subbed only (no English dub) - This was minor for me, but I would have loved an English dub for this.

Overall, it is a good game with a good story. If you are not trying to get all the achievements, it is really enjoyable.
