Since there weren't any proper guides on Steam or anywhere else on the internet, I decided to write one to help anyone struggling and I want the game to get a bit more attention.This is hopefully a helpful outline on how to get any achievement you're missing based on my playthroughs and the game developer's instructions.

Beware of minor spoilers.

Please feel free to comment any helpful tips you have.

Tips just in case:
- Choosing first choices builds up compassionate points
- Choosing second choices keeps you neutral
- Choosing third choices builds up cocky points
- Liking community users words of wisdom and game tips is important for when you want strengthen Emmett's bond with Vivi.

- Welcome to Videoverse

- A Friend Request

- Growing Closer

- Butterflies

- Return to Videoverse

- Left Behind

- Ready for Feudal Fantasy II Fall of Hanzo (Don't skip the Feudal Fantasy cutscenes)

- Anxiety

- Playing Games

- Em-otional(You get this while typing "vivi" in the Dolphin page near the end of the story but keep doing it until you see black haired Emmett)

- When Emmett met Violet

- Variety is the Spice of Life: this is done by liking enough comments, posting enough comments and reporting enough swears, negative and troll comments in every community. Also in chapter 2 click the open game magazine on Emmett's desk, log in and then type the cheat code in Emmett's profile page.

- Lots of Love: It's rewarded by liking enough comments.

- Lawful Good: It's rewarded to you by reporting enough swears, negative and troll comments.

- Team Markun666: Be friendlier with Markun666 over Zalor, interact with him positively in the communities and help him with his poster. It will pop up near the end of the game.

- A Kickass Poster: Help Markun666 with his poster by sending him drawings whenever the option is possible.

- Team Zalor: Be friendlier with Zalor over Markun666, help him out when he asks and be open with him about Vivi.

- Could it be: Like with Team Zalor Be friendlier with Zalor over Markun666 (ignore his poster request), help him out when he asks, be open with him about Vivi and persist when he won't open up. You should get it when you chat with him in near the end of the game.

- Friendship Over: Be unfriendly towards Zalor, don't help him when he asks, build up cocky points and insult/argue with him about his bad advice. He'll block you at that moment and the achievement shall pop up.

- First Impressions: Keep rejecting Vivi's friend request until the achievement pops up.

- Shy Guy: During the first video chat with Vivi choose to say it's weird and then choose to turn off camera when she asks. Then she will bring it up near the end of the game and that's when you will get the achievemnt.

- Rumors from a Relative: Comment to UncleFromKinmoku about what's happening, answer his 3 riddles correctly and accept his friend request.

- The TRUTH: After accepting UncleFromKinmoku's friend request, talk to him without being cocky and don't insult him.

- So Fluffy: Interact with Fluffy-Pancake in the communities, be nice to her and she'll send you a friend request.

- MarKilled: Keep reporting Markilled until Videoverse in the Chats tells you they're banned.

- Max Community: This will come to you naturally as you report trolls, negative comments and swears.

- It Came Recommended: In the Art Corner community there will be posts and drawings relating to The Pictures You Painted. Express interest in it. It's also important you don't neglect reporting trolls.

- Potty Mouth: In the Arts Corner community someone will post a drawing from The Pictures You Painted. The user YOUR_N1GHTm4re will comment "Is that the girly game?" and you can respond to her until that swear comment choice is available. Then Videoverse will call you out for it in the Chats the next chapter. It's also important you don't neglect reporting trolls.

- Belongs to the Gays: Basically whenever someone posts about being gay, comment nice things like congrats and such. It's also important you don't neglect reporting trolls. It will pop up near the end of the game.

- !SPOILERZ!: In chapter 5 when Markun666 posts a Nobunaga drawing in the Feudal Fantasy community, ask him about it and then someone will post a spoiler.

- A Remake of the classic Jellyfish title: in the Kinmoku Games Community when user named Snak3 mentions Pill Poppa for the first time (there's also a second time IIRC), choose to ask what Pill Poppa is about, he'll answer and the the achievement will pop up right there.

- I didn't Think You'd Find Out: During your first chat with Zalor, don't choose "No way that's private" when asked about Vivi. Lie to Zalor when he asks Emmett about girlfriends i.e. That Emmett is dating Vivi. After a few conversations, Vivi will reveal she heard gossip and you will get the achievement.

- This is Embarrassing: Emmett chooses the game when he has expressed romantic interest in Vivi by choosing dialogues like he wants to dater or kiss her and he has to have high enough friendship with her.

- Full Stop: Emmett chooses the game when he has no romantic interest in Vivi.

- Teenage Crush: It's achieved by the end of the game when Emmett has expressed romantic interest in Vivi.

- Best of Friends: Don't have Emmett be romantically interested in Vivi and develop their friendship at it's highest by being kind, choosing compassionate choices and using words of wisdom and game tips from users in the communities to comfort Vivi in Chapter 7. You also need to report trolls and negative comments and be friendly and helpful to the other users in the communities.

- In The Crowd: This happens at the end of the game when friendship with Vivi is high.

- Empty Seat: This happens at the end of the game when friendship with Vivi is low.

- It Matters: This happens at the end of the game when friendship with Vivi is high and you need to report trolls, swears and negative comments and be friendly and helpful to the other users in the communities.

- It's My Passion: This is achieved when friendship with Vivi is low and you neglect and ignore the communities.
