“I just got an iMac 20″ 2.1GHz (2006) at first it ran well no problems, but now the screen randomly goes black, the system still runs just black screen, if left alone it will go to sleep and can be awakened just fine as if nothing happened but later it’s black again. any advice would be appreciated.”

iMac screen going black is a quite common malfunction when we use Macs. I have collected several high frequent scenes when the iMac screen turns black:

Scene 1. iMac screen goes black randomly, and after turning black, Mac will shut down automatically. When you restart Mac, it will get right.

Scene 2. iMac screen turns black continuously no matter how many times you restart it.

Scene 3. When you are doing something on Mac, for example, watching a movie, the screen goes black suddenly, but the system runs still in the background.

Scene 4. It is ok with turning on MacBook Pro plugging in AC adapter, however, when you unplug the power cable, the MacBook screen will immediately go black and shut down.

These four situations are not all about iMac screen changing black. But we can solve all of them with the following method.

i surprisingly managed to escape on first try, and then i went back to get all the endings. great game and story-telling! love the mini puzzles that aren't too hard but hard enough to keep you going ^^

so far so good, i like the endings i've gotten. still trying to figure out if you can get into sector-L

Sadly that sector isn't in this gamjam version of the game. You can get an idea of what's inside if you fail either of the last two puzzles.

The full extent of the facility will be explorable in Claustrum (mentioned in the description).

Amazing game! Loved the mini game/puzzle aspect and just the general overall tone. I've only gotten one ending so far, but there's a feeling of unease/dread and of a big moral dilemna throughout the game. I loved it!

wow just.. wow!! This is an amazing game and I'd love to see more! If you ever get the chance, please make a 2nd game!!!! Cpu temp online. I'd love to see more of Andrew too :

Thank you for the kind words and I'm glad you enjoyed it!

I am actually working on the fully developed version of this game as we speak!

Very cool game ! Love the design and atmosphere ! Keep up the good work :)

Greetings brother. I really appreciate the way you have presented this game in a very well-short way.

I enjoyed the main part of the game.. the plot, ambiance, atmosphere, tension, etc. The puzzles are good, the sounds are very effective and the style is nice.

What a great short game it was. I liked the style and atmosphere. Original concept and something refreshing! Keep on the good work!

This was incredibly atmospheric! A great little game. I fully recommend.

The game is certainly challenging. Make one wrong option and back to the beginning you go. I wish there was a checkpoint system or safe rooms. (along those lines) the game is very atmospheric however, when you die the screen turns black and you hear horrifying sounds, i wish there was something more like image. https://site-4775208-7257-4898.mystrikingly.com/blog/convention-simulator-mac-os. But the game is really good! The puzzles are challenging (but can be solve) and the game gives you good world building. Good Job!

Thanks for the kind words! This is just a slightly improved version of what we made during the 48h gamejam. If we make a longer version we'll probably add checkpoints cutscenes etc. Glad to hear you still enjoyed it!

We'll make a mobile version in the future if we keep developing this game, for now that was just a mistake in the page. Disk o download.

EDIT: Android version now available
