Grim Diary Sneak Peak Major Changes
Hi I'm lepus the sole game dev of this game. It's been months since the last updates.This is the screenshots of all the major changes and additions to the game. New Kabo Village Caves Mob EncountersNew UI Improvement and New Addition Skill Presets. Potential Systema player can use an item's effect by fulfilling its requirements slots.After it’s activated it does have a potential to appear during battle to aid a player. Still an early concept,the activation during battle requires a different source. Prior to this concept a Character Equipments System is planned to be added. But changes to potential system.Still an early concept but here is blundle's House. Because of the story changes the blundle sisters will have their own house provided by kabos.This is all I’ve been working on for many months. If you’re wondering why the development is slow.Aside from being the only dev on this project. Funds used in this game came from my personal paychecks. Nonetheless I still continue to work on this project. The release date of the huge overhaul is still unspecified but not going to be this year. if you want to see my more frequent updates. here is my page.I’m sincerely thankful to people that support my work.https://www.facebook.com/LepusGameDevRead full article on Community Announcements (lepuscadenza)Patch NotesOfficial

Level Design Rework
Grim Diary ~ Level Design Rework Instead of choosing a path through UI. It will change to Emi exploring around discovering hidden passages. Instead of keep pushing new story chapters i think it will amount to nothing if the level design is not decent enough.the current design does not fit with the vision I have for this game. That's why the changes. And believe this will improve the game and makes the player feels like part of the grim diary world.Read full article on Community Announcements (lepuscadenza)Patch NotesOfficial
