Hello everyone! Hope you're having a good Halloween. I'm excited to announce the release date for the upcoming Catalyst Update.


That's just 10 days away! I hope you'll enjoy the new content as much as I enjoyed making it.
How will you access the new content?
A new door will be open after the end of act 2. Just follow the blue light.

Know a Youtuber, Twitch streamer, or other content creator who want to see play Photochemistry? I'm giving away free copies along with early access to the Catalyst Update to any content creator who uploads regularly, no matter how small the audience! If you or someone you know is a content creator, get in touch at http://mailto:[email protected].

Hello everyone! Hope you're having a good summer. I've been working hard during my free time over the past few months on a new content update for Photochemistry to flesh out the systems and lore of the game. I'm happy to now announce what I've been up to.

The Catalyst update (v1.4.0) will contain:
- 7 new puzzles (plus a few mini-puzzles)
- A new character
- 2 new types of particles
- A new area
- Lots of new lore
- An undo button

Here's a sneak peak of one of the new particles:
I also want to introduce you to the new character: Her name is Synapse and she's been around in this facility for even longer than you have. She might be able to answer some questions you have about your history and purpose.

Both Synapse and the new puzzles will be accessible just after finishing Act 2. I look forward to seeing your thoughts and puzzle solutions!

Additionally, the game's getting a Simplified Chinese translation. It will be available for all base game tutorials and menus as well as the new dialogue with Synapse.

I'm not quite ready to give an exact release date for the update as I'm starting classes again soon on top of my regular job, but I'm committed to a release within the next few months.
