Harold Halibut uses a virtual texturing system where all textures are combined into one large "mega texture". This technique ensures the handmade look is preserved at the highest quality, but results in a larger download size.

Yes! Harold Halibut is now available on Mac via Steam.

Yes, Harold Halibut is Steam Deck Verified. If you experience any video playback issues (such as SMPTE color bars during cutscenes), try installing Proton GE as a workaround.

Harold Halibut requires a dedicated GPU (minimum NVIDIA GTX 1060 or AMD RX 480). Integrated Intel graphics are not supported and will cause visual issues such as black or blank screens during cutscenes.

This is a known video playback issue on Steam Deck. To fix it:

• Install Proton GE (a community build of Proton with additional codec support)
• In Steam, right-click Harold Halibut → Properties → Compatibility → select Proton GE

If you're experiencing graphical smearing or blurriness, try adjusting these settings:

• Switch upscaling from DLSS to STP
• Disable HDR
• Disable Dynamic Resolution
• Turn off VSync (this can also help with stuttering)
• Reduce Fog Settings to Medium

The "Slow Bros" achievement requires 15+ hours of in-game playtime within a single playthrough. Time spent in menus or dialogues does not count — only active gameplay time. If you're close, you can leave Harold idle in the game world to accumulate time.

Yes, some achievements are missable. Our best advice: talk to everyone each day. Key missable achievements include:

• "Managing Upwards" — Make sure to complete the related interactions when available
• "Exchanger Arranger" — Available in Chapter 4.2, don't miss it
• Chapter 1.1 achievement — Try to leave the room three times before proceeding

You need to collect all 71 notebook entries. Some entries are missable — they require talking to the right person before the day ends. Make sure to explore thoroughly and talk to every character each day.

Warning: Loading a previous chapter via Chapter Select will reset your total playtime to what it was at that chapter's save state. This can affect time-based achievements like "Slow Bros". Use Chapter Select with caution.
