First and foremost - The game loads quickly to 90% & then stays there for a LONG time. Don't let that distract you from enjoying the game.

Don't close the game, it's not stalled. Wait enough time & you'll be rewarded by one of the best (if not the best) games in genre

1) The game happens in chapters. During the chapter your actions are more or less linear.

During the intercourses you are free to roam opened areas, search for extra stuff, fuck or mess with girls.

Note that not much free roaming activity will happen before you'll talk to Aemi after gaining control over the Laboratory.

And in order to use it on Vivian - You need to get to discuss specific topics with Aemi and Vivian. After that you'll get possibility to "play" with Vivian as well.

But you 100% can "unlock" both girls before Hydroponic Section & than just hoard tools and machines.

2) With all due respect to creator - his help system currently is not that helping, so I'll duplicate it here.

You are moving with W,S,A,D, activating objects and talking with girls with E, relocating stuff with R(later in the game). Shift - running, Space - jump

You can also use a flashlight with L(although i was fine with not activating it even once) and change equipment settings with F (also later)

F1 triggers help screen with advice on what to do right now(if you're lost)

F4 shows the affection screen. Note that affection does matter and some options will be available when the girl affection is more than 50 (or 100)

F5-F8 - quicksaves the game to slots 1-4. F9-F12 - loads the game from the corresponding slot

Esc - launches menu, TAB - opens personal menu where you can activate items

3) Now to actual gameplay: as strange as it sounds - the best way to experience this game is to loose all fights & tasks

That does not relates to hacking minigames - if you fail them you need to do it again. Everything else - loose & enjoy!

Or you can win minigames with "ctrl+w", but it's funnier to actually solve them

4) I would really advise to try the game by yourself, and use the item list only to double check. But if you really feel you need to & not afraid of spoilers - lists are below

Note - all found equipment is not active unless you tank with each girl & "show her equipment you found"

5) Poker - If you want to try to loose - choose the punisher. General loss is boring (nothing happens). Choosing Aemi/Vivian brings extra scenes (but not equipment)

7) The guide is incomplete. I'm still not sure I found EVERYTHING Plus there will be at least 1-2 more rooms with (hopefully) more devices & sex toys.

Obviously everybody is hoping for more rooms with more devices. And maybe (although problematic by all means) - an extra girl?!

Can be used in fight. Not a big deal, since it's better to loose fights anyway

Not available for Vivian until you take over Hydroponic section. Also, available only if you loose the fight in maintenance area. Not moveable!

Allow to summon girls & play with the toys (if inserted), activates by "if there anything ..." conversation

Can be used in later stages. Note - activation occurs from Vivan's conversation, only if her arousal >50

After "milking" of both Vivian and Aemi - you can move machine to hangar

Aemi gets the option ho wear it at some point. Definitely available after Living Quarters
