This game is amazing! I like the characters and the voice-acting as well as the visuals. I like that they are very different from each other and how they respond to the questions. My favorite is Mr. Red, especially when you ask him about Ms. Yellow. It is too bad I couldn’t meet Ms. Yellow since I heard so much as her.  10 / 10

I really enjoyed your game, although the one part with the circuit being "bulletproof" really threw me for a loop until I saw someone else's solution.  Are you sure that's the word you wanted?

I'm looking forward to the full version though!

I really enjoyed this game and actually played this all the way through. The game is well put together and I highly recommend it to those that are wondering how to play. I played it using the itch.io app, I am going to leave the gameplay video here. I also played this for my Indie Game Showcase Season 2 Wave 2 Part 2.

Looking forward to more of this game:

Wow! Really interesting story guys! I just loved playing the game, I wasn't the best detective at first but I definitely got better with time haha, I loved the background music too! keep it up!

How do I play the game? I know how to extract it and such. But, when I do I can't find the file to open the game. I think it might be because I accidently clicked to always open rar. files with internet explorer. :/

When you extract the .rar you should get a .exe file that starts the game. 

If you want to change how you open a file then you can change it by following this link:

Hope this was of any help. :)

Any chance of a browser-playable demo?

I am sorry, but the game uses software that doesn't work with browsers. :/

Aww. It sounds great.

How do you convert it from a .rar file?

Download WinRAR or 7zip. They are free software that will convert .rar file archives. I can't remember, but I think windows might have a default ability as well if you right click on the .rar you should see the option to "extract" the files.

Thank you so much for your help!

I had the same problem as ErrArachnica - got as far as asking Red about the contradiction between cataloging everything and destroying the circuit board immediately, and a new piece of info was added in solid purple without readable text. So I couldn't get any further. 

Shame, as I was starting to enjoy the game.

We are aware of this problem and will fix it in the next update. The pink statement without any text is not necessary to progress in the game. There are other contradictions that move the game forward.

0.2 download says it only contains the demo?

asked mr.red about promptly destroying the circuit board and the note block is error pink with no text


We are aware of this problem and will fix it in the next update. The pink statement without any text is not necessary to progress in the game. There are other contradictions that move the game forward.

I really enjoyed the game, although I didn’t finish it yet, I like the art style and I’m sorry I sound a bit tired in this video

Hey Conkergoo! 

Wow! Really cool that you streamed yourself playing the game! I think I saw your name on Discord! Feel free to give us any of your feedback there!

Much love,
