In the Steam and mobile versions of the game, there are eight achievements you can get. Some of them occur naturally when you play, but some are a little more difficult.

Medium Well Done -- Finish the game at least once.

Hear Me -- Play the entire game with the commentary mode active. You don't have to actually listen to each commentary; you can just click past if you'd rather. But to win the achievement, you have to leave commentary mode on until you finish the game and credits.

Hello Joey -- Finish the intro and meet Joey.

When do I meet Joey?

Medium Lie -- When you go to visit Susan Lee in the hospital, get the guard to let you in on the first try.

How do I get in to see Susan the first time?

Pacifist -- Talk to the Deacon without letting Joey beat up on him any more than absolutely necessary. To do this, select Rosa's option every time. To be specific, choose: -- What does he want? -- What is after him? -- Who is after him? -- Give her a chance -- Try and give hope -- Because nobody will help

Savior -- Save the Deacon from the demon in the immortal plateau.

Can I save the Deacon?

Crowd Control -- Don't try talk to Joey in public. That is, don't left-click on him anywhere but in Rosa's apartment. If he starts the conversation and Rosa responds automatically, that's fine.

Family Historian -- Get Joey to tell you everything he knows about your family. (Well, everything he wants to tell you, at least.) To get as much info as possible, look at the three family pictures before and after you meet Joey, then talk to Joey in your apartment about every item in "history" until he starts to repeat himself.
