Geocells is a continuously evolving series of games that aims to expand beyond existing logic puzzle solving experiences. In this spirit, the Geocells version 2.0 update brings a full rewrite of the entire code base from the ground up to support future development and to bring in the first batch of major improvements. This update is completely free for anyone who owns Geocells Tricells. While these changes require an update to the save data format, extensive efforts and testing have been invested to ensure that existing save data will be automatically upgraded smoothly. https://www.youtube.com/watch?v=gOW2ShjXo3M Following community feedback regarding challenges and progression, the challenge levels have now been merged with the regular levels, allowing all 6 gems to be earned in a single playthrough. Additionally, the no mistakes challenge has been replaced with a new random rotations challenge which intermittently changes the orientation of the puzzle, after correctly identifying a certain number of cells. These adjustments should provide additional longevity and replayability to the existing puzzles while reducing repetition and grind for completion. For those looking for even more gameplay and challenge after a regular playthrough, some new free post-game bonus levels have been added. These levels provide challenges that reach far beyond the difficulty of the regular levels. In order to support players to experience all the content at an accessible level, we have added freely available hints that provide guidance on where one or more cells can be identified using logic, without giving away the final result. Combined with the new auto-disable completed clues option, this should assist players to more easily identify the next step in solving the puzzle without needing to engage in treasure hunting (or 'pixel hunting') through clues. On the topic of new assists, the new freedraw notes provides a mechanism for indicating and storing information outside of ones head while playing a level, which can be particularly helpful for more advanced puzzles. Freedraw notes also provides a creative outlet for users to connect with their inner artist and draw beautiful (or not so beautiful) artwork masterpieces. Feedback from internal testing has been very positive, especially about the toggleable semi-transparent overlay that can allow you to see your notes while continuing to play through the level. For now, these notes are limited to a single layer with a limited color palette, and all notes will be cleared upon completing a level. We look forward to seeing how the community makes use of this feature. A number of quality of life improvements have been added for clue highlights including a clear all highlights button, support for highlighting disabled clues, and adjustments to how highlighted cells are displayed for better visual clarity. Thematically, a new dark visual theme has been added for those who prefer a softer and darker visual experience. In terms of music, players can now choose the Geocells Quadcells theme, a new Geocells Ambient track (designed for a more meditative experience), or the existing Geocells Tricells theme. We are also adding a few bonus features such as official Mac and Linux support and free demos for all games in the Geocells series (all available for Windows, Mac, and Linux).** All of these features are also available in our newest release, Geocells Quadcells. This is the first major update in the Geocells series and we invite you to join us in celebrating the joy of logic puzzles by playing some Geocells games today! Finally, we would like to take a moment to thank you for all of the feedback and reviews weve received to date. They are greatly appreciated. We will continue to consider community feedback as we strive to deliver the best puzzle-solving experiences possible both now and into the future. Warm wishes from us to the logic puzzle community (current and prospective), Scott and Georgie Addendum: Steam achievements are currently in development, but were not complete in time for the release deadline. Alongside achievements, we have a variety of other exciting features in development that were excited to share with you once theyre ready. **The free demos will be made available once we have resolved some last-minute issues.
