Blue Prince Patch 1.02 Adds Fixes and Steam Deck Support

Welcome to Mt. Holly, a creepy, mind-bending manor where no two days—and no two rooms—are ever the same.

In Blue Prince, you take on the role of the heir to a mysterious estate, navigating its constantly reshuffling blueprint. Every closed door is a choice, and behind every choice is a new room with unique secrets, puzzles, and surprises. One day, you might draft a cozy sitting room. The next, a death trap. It’s all about strategy, exploration, and luck.

Your ultimate goal? Uncover the elusive Room 46. But that’s easier said than done, especially when the house resets itself each morning and only permanent upgrades (if you’re lucky enough to find them) carry over.

Along the way, you’ll unravel a story involving blackmail, political scheming, and a missing children’s author. Oh, and did we mention the house is basically alive? Yeah. No pressure.

Steam Deck Fixes + Technical Tweaks

Now onto the patch itself. One of the headline additions in Patch 1.02 is better support for Steam Deck users, thanks to new video file redundancies that improve cutscene playback. It does make the game a bit chunkier in size, but performance wins are worth it.

Other key updates:

• Fixed a major bug where room rarity data bled between save files (yeah, that’s why your rare rooms were disappearing).
• Lab machine camera lock issue? Gone.
• General polish pass: typos, formatting, and improved control customization.
  

Late Game Bug Fixes (Spoilers Ahead!)

Some pretty serious issues in the late game have now been addressed:

• Softlock while accessing menus during boat travel? Patched.
• Hardlock at the mystery door with the basement key? No longer an issue.
• The TOOLSHED now spawns more than one item (as it should).
• Exploiting the Coin Purse in a certain secret room? The devs noticed. It’s fixed. Sorry, cheaters.

Other tweaks include improved HDR lighting, animation fixes in key cutscenes, and updates to missing or untranslated UI elements.

Final Thoughts: The Mansion Grows Stronger

Blue Prince may be a surreal roguelite full of mystery and magical realism, but behind the curtains is a dev team that clearly listens. The 1.02 patch not only fixes some deep bugs but also brings quality-of-life updates that make the game more accessible and immersive across platforms.

If you’ve been waiting to return to Mt. Holly—or you’ve been hesitant to step through that first door—this patch might be the sign you’ve been looking for.
