- Sales in Russia suspended due to connection issues - 25 March 2026
Detectives, Due to ongoing technical issues affecting connections to our servers, we’ve decided to suspend sales of our games in Russia. We don’t think it’s fair to sell a game in a region where we can’t maintain a reliable quality of service. Players in Russia often have trouble connecting to our servers, and unfortunately this is beyond our control. There are government-level restrictions that affect certain types of connections to servers outside Russia, and recently the situation has been getting worse. We’ve implemented many workarounds to reduce these issues, including better global server distribution, proxy servers, and dynamic rerouting. However, the restrictions keep changing, and it has become a constant game of whack-a-mole. Unfortunately, we also cannot legally host servers in Russia, so for now there is nothing more we can realistically do. We’re very sorry we had to make…

- Parallel Experiment delayed to June 5th, 2025 - 25 February 2025
Detectives! We planned to release the game on March 6th and were working day and night to meet that deadline. However, unforeseen obstacles significantly slowed our progress. In our effort to deliver the game on time and at our high standards, we had to cut some "nice-to-have" elements: extra features, optional puzzles, and even the mobile version. But we soon realized we had cut too much. You deserve to experience Parallel Experiment as we envisioned it from the beginning. We can’t release a game missing key elements. It wouldn’t be right. So we've made the difficult decision to push the release to June 5th, 2025. This extra time will allow us to polish every aspect of the game and restore all that we cut, ensuring a perfect Parallel Experiment experience on day one. We’re truly sorry for letting you down, but we believe it's better to launch a complete game with all the bells and whis…
