Basic walkthrough of the game with all the achievements, including the cheeky one, and how to get them.
 
 

Introduction

Time to break out the (companion) cubes! This short game is you, an “examiner,” and a bunch of cubes and buttons everywhere using a simplified version of gate logic to get from one room to the next in (what should be) a straight line.
 
 
Of course, that’s never gonna happen.
 
 
 

Walkthrough

Let’s take a walk, shall we?
 
 
Room S: This is the place you start the game
 
 
There are three achievements you can get in this room, one of which is missable. When you appear, you’re under an arch made of cubes. Pull it apart and pick them up until “Mark” sounds off about his favorite cube.
 
 
1/28: This one is special
 
 
Now, pick up any cube, stand under the speaker in the NE corner of the room. Look up at it, and jump. “Mark” will again complain.
 
 
2/28: Talk to me
 
 
Now head to the NW corner of the room, and repeat with the camera. “Mark” will again complain.
 
 
3/28: Build to last
 
 
Achievements 2 and 3 can be done in ANY room, but the run timer doesn’t start until you head into room 1, which we’ll do now.
 
 
4/28: Step by Step: Walk from the starting room into the first.
 
 
Room 1: Cube, button, door. Done.
 
 
5/28: Cubes Only: Step on the button, hear Mark complain
 
 
6/28 Already Quite Challenging: Finish the first room.
 
Room 2: Just Watch. “Mark” thinks he’s funny.
 
 
7/28: Brilliant
 
 
8/28: This is getting out of hand
 
 
Proceed to Room 3
 
 
Room 3: Two cubes, two buttons, door.
 
 
9/28: Now there are two of them
 
 
Room 4: One red button, no cubes? Wait for it…
 
 
Since we’ve got a second until “Mark” stops yapping, turn to the right and look through the crack in the wall in the corner:
 
 
10/28: I like this view (missable)
 
 
A red cube will fall to the floor from about the door. You know what to do.
 
 
11/28: Loving that Song
 
 
Room 5: Red cube, blue cube in box, etc. “Steve” introduces himself. Sounds just like Mark. Odd…
 
 
12/28 The most important room
 
 
Room 6: The sky is a lie!
 
 
13/28: The sky above
 
 
Room 7: The second cube is to your right, behind the machine.
 
 
14/28: Stars
 
 
Room 8: More complex puzzle
 
 
15/28: Halfway through
 
 
Halfway through the game.
 
 
Room 9: We’ve seen a slightly less complex version of this puzzle. Proceed as normal.
 
 
16/28: You’re doing great
 
 
Room 10: “Bob” makes his appearance
 
 
17/28: This is Bob speaking
 
 
Room 11: Tiny room, very simple.
 
 
Let the cube fall out of the box, stand under the box, and jump.
 
 
18/28: Don’t get your head stuck (missable)
 
 
Cube, button, you know the drill.
 
 
19/28: Small and smart
 
 
Room 12: Lots of cameras
 
 
20/28: Being watched
 
 
Room 13: Don’t attempt to solve this room. “Bob” is trolling you.
 
 
Go to the left, and manipulate the piece of plywood to make a ramp into the next room.
 
 
A cube will work just as well, and is less of a ha*sle. (From Na)
 
 
21/28: Through the wall
 
 
Room 14: light math required.
 
 
22/28: Reorganization
 
 
Room 15: Do all the things.
 
 
23/28: Back online
 
 
Room 16: Last puzzle, most complex
 
 
24/28: So many cubes
 
 
Room F: You’re done with testing!
 
 
25/28: Rooms solved
 
 
26/28: Adorable
 
 
Now you’ll be kicked back out to the main menu (because you’re done), and your finish time will be displayed. You can’t go back, but you’ll get a popup about Party Mode being available in the options. Let’s go there and turn it on.
 
 
27/28: Time to Party!
 
 
28/28: Completion
 
 
And… There we go! All the achievements in a single run. Those that are missable (you can’t get them without starting again) are tagged inline.
 
 
One more thing: as of this writing, there’s a geometry issue in the back of Room F that allows you to leave the map and do the Forever Fall. Hit ESC to return to the Main Menu.
 
 
 

Conclusion

I originally intended to just do an achievement with comments for “missables,” but as I tucked in, I couldn’t help but comment here and there.
 
 
Let me know if you find anything I missed or got wrong, have a question or what have you.
 
 
See you in the comments!
 
 
Shoutout to Na, who gave me the way to get that final achievement I needed to 100% the game.
