Minigame
In this event, players can use the event currency Mansion Invitation to challenge the Limited-time minigame Game Development Club's Cleanup Operation. Players will be controlling Arisu (Maid) or Yuzu (Maid) to fight enemy in a rouge-like gameplay.
The game screen will be vertical during the minigame gameplay.
Each time you clear a stage, you can select a specific buff effect and move on to the next stage.
Certain buffs can be picked up more than once to upgrade the effect.
The minigame will have a time limit, and each time you move from one stage to another, the time limit will be extended by 45 seconds.
The minigame will end in the following scenarios:
You cleared all the stages.
Your character's HP in the minigame goes to zero.
You ran out of time.
You give up in the middle of the game.
Play the minigame once a day to unlock the sweep function. Sweep will give you the reward from your "highest stage" clear of the day.
The Sweep function will be reset at 4:00 A.M. (JST) every day.
There are two difficulty levels for this minigame: Normal and Hard.
It seems like you can unlock a secret by inputting a certain command in the minigame Student Selection screen...? Try to figure out what it is!
Minigame Tips
You can move your character by sliding anywhere on the screen. Stopping movement will make your character attack and auto-aim at the enemy.
There is no dedicated shooting or aiming button. You have to stop your character from moving in order to shoot.
You can attack significantly faster by moving lightly to any side instead of waiting for the animation to finish. As such, the ASPD buff is largely useless.
There are 3 types of characters available: Arisu (Maid), Yuzu (Maid), and a Hidden character unlocked by swiping the Secret Command aka the Konami Command.
Arisu (Maid) and Yuzu (Maid) is an attacker that deal ST damage on hit but has a higher base damage at 30.
Hidden character is an attacker that deals AOE damage on hit but has lower base damage at 16.
Recommended buffs are the ATK UP, Extra Forward Bullets, Piercing, and Ricochet.
Burn buff DOT damage is really low, but it's good to shave off HP in the long run.
Ice buff is decent to slow melee enemies, but most enemies are ranged, so it's not that useful.
Extra Diagonal Bullets aren't bad, but they are useless without the Ricochet buff.
Minigame Reward
Normal and Hard difficulties contain the same reward.
Players will be able to obtain different rewards upon reaching the stage count. At stage 10, the reward will differ depending on whether you defeated the boss or not.
