Update Notes for version 2026.08.07
This is a small update, with one visual update and some minor tweaks.The boulder art was some of the oldest in the game, and some of the first I made using Aseprite. It has now been replaced with new boulders that better match the rest of the game, and my improved abilities, in particular the new dirt and background tiles that were introduced post-release.Some text snippets have been updated along with other minor tweaks.Read full article on Community Announcements (Renonsical)AnnouncementsOfficial
Swedish Translation
This update includes one major new feature, a chamber fix, and a couple of new bonus chambers.The Portsmoor Abysm now has a Swedish translation available. This may be significant for those who would prefer to play the game in Swedish, but also because it means the game is now ready for further translations if I can find people willing to perform the actual translation work. The episode 3 chamber Varkár has been updated to only have one known solution.Two new chambers have been added to the bonus episode, rounding the number of bonus chamber out to 18, the same as all other episodes. This means that the game now has a total of 90 chambers.A couple of very minor issues have been fixed.If you find issues with the language used in the game, please report to me and I'll try to fix it.
