Development Update #5: Steam Next Fest and Voice Cast Trailer Incoming!
Hey everyone, Lina here with a new update! 🎴👾
First off, thank you all so much for your very prompt responses to our Backer Survey last month! We’ve got nearly everyone’s preferences now and are so excited to start working with all of the folks who chose creative rewards! We’re also pleased to say that the full in-game credits with all of our backers will be included in the coming Demo Update, which we’ll get into in a moment, but first…

Our current estimate for Episode 1’s development progress is 62%, which has been a bit slower with some of us being students with finals, but our great pace before has kept us on track! Here’s the breakdown:

As we enter the summer months, we’ll be picking up a lot of speed with the finish line in sight, we don’t foresee any delays with hitting our target release window in Q3 2025!

We’re excited to formally announce that Kumitantei will be a part of Steam Next Fest’s June 2025 edition, running from June 9th - 16th! Next Fest is an incredible triannual showcase of upcoming games from thousands of talented developers, featuring tons of free demos to try out and wishlist! If you haven’t already been checking them out every few months, you definitely should be!
If you also haven’t already, please wishlist Kumitantei on Steam! It helps us way more than you’d probably think!
To coincide with our participation, on June 9th we’ll be releasing our biggest update to the Demo Version yet, as well as a brand new Voice Cast Trailer via premiere on our YouTube channel! We hope to see you there!

As we’ve been alluding to, we’ve got a big update coming to the Demo on June 9th! This one’s gonna be bringing more QoL improvements, new pretty Episode Start and End graphics, the complete in-game credits, and most importantly… voice acting! The whole cast have been lovingly brought to life by an incredibly talented group of voice actors, and we’re so excited to reveal who’s playing who and give you all the opportunity to hear their performances in action next week!

As you can see, the Prologue is now properly titled “The World They Knew”. While it’s always had this name internally, we just didn’t have an opportunity to share it until now! Yay, something new to theorize about!
Since we’ve been building up a lot to share during Next Fest and through the Voice Cast Trailer, this Backer Update is slightly shorter than our usual ones. It’s very important to us to keep you all informed, but we hope you all can understand waiting an extra week for the big stuff. However…

That’s not to say we’re quite done today! For all of your support and patience, we’re giving you guys the first real look at a location you’ll soon become very familiar with! Welcome to the bunker’s eerie and imposing Trial Room!

This will be the setting of the Clinical Trials, where the class will be forced to debate the truth and eventually condemn one another to death. It certainly fits the part, wouldn’t you agree? You’ll get to see a more thorough look next week in the Voice Cast Trailer, but this first peek is just for you guys! 🎴🖤

That’s about all we’ve got to share for this little amuse bouche of an update, we really hope you’ll all join us for the main course next week! Thank you to each and every one of our backers for your support and patience, it’s genuinely such an honour having this amount of faith in our team. We’ll try our best to keep living up to (and hopefully exceeding) your expectations!
