Antenna Dilemma has a total of 10 Steam achievements, 9 of which are missable with just one being story related. All achievements can be earned in one full playthrough taking around 30 mins and a second much shorter game taking around 4~5 minutes to complete.

There is a degree of ambiguity surrounding a number of achievements for Antenna Dilemma and the Dev posted some hints/clues regarding a number of them in the discussion boards, as seen here...
https://sp.zhabite.com/app/1027990/discussions/0/1679190184058861786/

I have covered both the solutions and answers to these achievements in this guide and have made use of spoiler tags for those that do not wish the game handed to them on a plate.

Note that at the time of writing, Steam is still "learning about this game" so achievements will not yet count towards profile totals, I'm somewhat unsure of the "learning" process, but given the positive reviews, it should only be a matter of time until they count towards profile totals.

At the time of writing, there are two DLC packs available for Antenna Dilemma...

https://sp.zhabite.com/steamstore/app/1066100/Antenna_Dilemma__Supporters_pack/
https://sp.zhabite.com/steamstore/app/1066101/Antenna_Dilemma__Soundtrack/

The first DLC is a supporters pack contains goodies including...
- Game screenshots from early versions of the game
- Mock-ups and handwritten notes about the game story making
- A document which gathers all fun facts about game inspirations, Easter eggs and much more
- A dozen of original wallpapers made for this DLC
- Original drawings of stickers made exclusively for the game by Crazy Kraken Studio
- How to get a special "Supporter" role into the Goloso Games Discord
- And some other surprises...

The second is an OST soundtrack composed by Philip Aldous.

These DLC packs do not add any content to the game and neither are required to be able to 100% the game. If you enjoyed the game (which I'm pretty sure you will) and would like to support and see more from the Dev then why not make a little contribution to their efforts. As well as receiving a warm fuzzy feeling in exchange for your DLC purchase you will also receive some digital goodies.

Box turtles are our friends.
***MISSABLE***

During your first full playthrough of Antenna Dilemma, upon first entering the TV Repair Shop you will encounter a Box Turtle, which blocks your way, preventing you from obtaining the antenna and cap, at the right side of the shop.

This turtle is dealt with by placating it with a salad, obtained from the vending machine outside. Before you give the turtle the salad, head to the area to the right of your house labelled "Antennas" with a large advertising billboard on the right and left, and a broken one in the middle.

Collect the Metal Bar from the Broken Panel in the middle of the area and then head back to the TV Repair Shop. Inside the Shop, use (or rather try to use) the Metal Bar on the Box Turtle to obtain this achievement.

Cube of Fortune.
***MISSABLE***

The Dev advises the following hint in the discussion boards for this achievement "You need to use the main menu's remote control. The symbols on one of the two panels in this office, maybe that's something."

The solution for this achievement is found in The Dice's office, in a cut scene near the end of the game (good ending)...


Click on the above image to enlarge.

The solution is to press the following buttons on the remote, found on the right side of the screen at the main menu, ↑ ↓ ← ← → ↓ and then OK.

See video walkthrough part 1 at the 0:30 mark for further help.

Henri Dotsquare.
***MISSABLE***

In the second half of the game you play as a circle character called Alfred and after an initial introduction between Alfred and Cube Guy (and a minor accident) you are prompted to return to your ship to contact "central".

After getting a damage report from your ship's computer, interact with the Dashboard on the left to try an initiate comms. Unfortunately, you have forgotten your emergency password and you need to complete three math puzzles to reset your password.

The solution to the first puzzle = 14
The solution to the second puzzle = 11
The solution to the third puzzle = 18

See video walkthrough part 2 at the 1:28 mark for further help.

Honey cube.
***MISSABLE***

The Dev advises the following hint in the discussion boards for this achievement "You have to call a family member. Special thanks to this person".

The solution for this achievement is found in the games ending credits, in a section headed "Special Thanks".

The solution is to dial the number in the credits (6268) from the phone in Cube Guy's home.

I'm going on an adventure!
Finish Chapter 1.

This is the one and only story related achievement in Antenna Dilemma, which pops when you reach the end of Chapter 1 (good ending).

Kind regards, C432632.
***MISSABLE***

This achievement requires you, as Cube Guy to place a sticky note, excuse/reason every time that you are prompted to do so when you break a law. Then later on when playing as Alfred the circle you need to read the sticky notes placed earlier by Cube Guy.

The pad of sticky notes is found on the table, to the right of the phone in Cube Guy's home, so make sure to grab these before you leave the house.

The times when a note should be left are as follows...

1. When you exchange your "Bill" (money) in the TV Repair Shop Cash Register for "Coins".
2. When you break the Vending Machine outside the TV Repair Shop because it stole your money.
3. When you open your neighbours mailbox.
4. When you rummage through your neighbours drawers (inside their house while they are not looking).

Then later on in the game when you are playing as Alfred the circle, you need to examine/read the second, third and fourth sticky notes left by Cube Guy before you leave town. (For me the achievement popped after I read the note on the vending machine, I did not have to read the note on the Cash Register in the TV Repair Shop).

I have placed time markers on my videos at the end of this guide for each time a note was left or read and when the achievement popped.

My favorite show, finally!
***MISSABLE***

The Dev advises the following hint in the discussion boards for this achievement "You can call someone who will help you to watch the show. Someone VERY influent, maybe you have heard his number somewhere".

This achievement requires a short second play of Antenna Dilemma (to get the bad ending) after you have completed your first full game (which is the good ending).

Upon starting a new game, once you gain control of Cube Guy, head over to the phone and call The Dice directly. The number was shown in the cut scene near the end of your previous game where the maintenance worker called The Dice to report a problem.

Call 3423.

One squarinara with ham cubes.
***MISSABLE***

When playing as Cube Guy, the first time after leaving your house, examine the advertising billboard above the door to your home, on the left side of the screen.

This will give you the number for a pizza restaurant, with the number in hand, head back inside your home and call the restaurant to try and order a pizza to earn this achievement.

See video walkthrough part 1 at the 4:04 mark for further help.

Tastes like cardboard.
***MISSABLE***

When playing as Alfred, after calling "central" inside your spaceship and obtaining a survival kit, rice cakes and a cookie, head down to street level following the path Cube Guy took to get up to the roof.

You find Cube Guy laying on the ground and a lengthy conversation ensues, at the end of the conversation, Cube Guy says he is hungry and asks for some chips, to earn this achievement, give him your rice cakes.

W.A.F.F.L.E.S
***MISSABLE***

The Dev advises the following hint in the discussion boards for this achievement "You need to use the main menu's remote control again. The letters are separated with dots. It probably means something."

The solution for this achievement is found looking at an alphanumeric keypad...

The solution is to press the following buttons on the remote, found on the right side of the screen at the main menu, 9233537 and then OK.
