We’ve poured our hearts and souls into this game, and we sincerely hope you enjoy every minute of it.

This release marks a colossal milestone for our tiny team. Parallel Experiment is by far our most ambitious project yet — and with only 7 of us, it’s been a wild ride. The scope was big, the technical challenges even bigger. But today, we’re proud. We’ve built something we believe is truly special — and we’re thrilled to finally share it with you.

Thank you for your incredible support and patience. We hope it was worth the wait. Please accept our deepest gratitude.

Parallel Experiment is now Steam Deck Verified!

Unsolved Case and Unboxing the Cryptic Killer also run smoothly on Steam Deck, though incorrect button prompts may occasionally appear. A fix is coming soon.

Anyone got me beat?

Unsolved Case servers are back up. Fixed by turning them off and on again 😅 Were down for the last ~3 hours, investigating why

@thatguy8455 Working on it! Sadly, the new game won't be out this year. Dialing in co-op puzzles takes time, and we want to get it right.

However, we have other cool stuff planned for this year, so keep your eyes peeled!

@MdhtJmal Good point

[Eleven Puzzles @elevenpuzzles]

Interesting, you have not mentioned the puzzles most players find really hard - like pipe puzzle in the beginning or moving platforms near the end 🤔

Thanks for the list, that gives me something to think about!

Especially the bar puzzles are puzzling... They are optional extra-challenge puzzles, but lots of players complain they're too hard regardless.

P.S. Trick to the Gargoyle was that you can change combination between partial pours 😉

Another awesome review from https://t.co/qER8P8Ecvm

TL;DR:

"Parallel Experiment offered a unique co-op puzzle adventure that I will never forget anytime soon, with its compelling narrative, ingenious puzzles and immersive presentation, While a few side puzzles were frustrating, they were just a drop in the ocean compared to the huge number of meticulous and brilliant main puzzles. If you’re looking for an engaging and unforgettable mystery to enjoy with a friend, this one is definitely worth playing."

Cool Parallel Experiment review, worth a read! https://t.co/uZXSdhwVWm
Thank you 🙏

For the last couple of months, we've been working hard on Parallel Experiment. What exactly, you ask?

First, there were some bugs at launch. Thankfully, we managed to fix all the major ones - and a ton of smaller ones too. We've released eight patches so far, and the game is in a really good place now! To make sure our future titles are as bug-free as possible, we've partnered with an external QA team. From now on, many (MANY) more people will thoroughly test our games before release, which should mean better quality and happier players.

Secondly, we're working on the Parallel Experiment 1.1 patch. It's going to be a larger update that tweaks some puzzles and smooths out a few rough edges here and there. It won't be a dramatically different experience, so it's perfectly safe to play now, but we wanted to give you a heads-up that it's coming.

And lastly, we have a few other exciting things cooking… but we can't talk about them just yet. Stay tuned!
