It's a good game, but it's also a gacha game and comes with all the pitfalls of that genre. Also, KLAB accounts are aweful. Will update this review if I am unable to reclaim my account after migrating to a new computer.

Update: Logged in to my KLAB account on the new PC. Datalink showed I have not logged in in 373 days. I have been actively playing for the last year. I will be ending my subscription and fully removing this game from my library. I strongly advise no one play this game or have any dealings with KLAB in the future.
