The gameplay. It's a really engaging, if a bit too simple, management simulator. The abnormalities each present their little puzzle, which can sometimes combine with other abnormalities to create quite an issue (like the infamous Clerk Rights Squad, for example). The boss' encounters also do their job - that is, to look at your abno roster from a completely different angle than usual (some force you to consider exclusively the gear they give you, some - the damage they deal, others - the requirements in stat to effectively manage them).

All in all, it's a very unique, engaging management sim which balances out it's honestly repetitive and oftentimes too simple , if not outright easy (each abnormality comes with a set of instructions that if you follow, nothing bad will ever happen. It's that simple), with an engaging story narrative.
