Patch 12
✨ New Content 1. Brand-new BGM for Level 1 & Level 2 We are thrilled to announce: Level 1 and Level 2 now feature brand-new background music composed exclusively for this game by Panagiotis Chartas! Experience enhanced atmosphere and immersion—put on your headphones and revisit these levels! 2. New Mode: Sandbox Mode This update introduces an extremely early-stage Sandbox Mode, primarily for testing future numerical changes and system adjustments. It currently consists of two sections: (1) Existing Content Sandbox Freely experiment with current character stats and all items to stress-free test various builds, combinations, and playstyles. (2) Future Content Prep Zone (Modification Area) This zone prepares for upcoming versions that will modify existing characters, weapons, attributes, and items. It does not introduce new content but lays groundwork for future major balance adjustments, stat iterations, and system optimizations. Currently in its foundational prototype stage, corresponding features will be gradually unlocked in the future. 3. Acknowledgments Special thanks to all players and friends who contributed game assets, content, feedback, and suggestions! Your support has made the game more complete and enjoyable.

Patch 9
1. Camera shake is an optional parameter that can be set during testing. 2. Weapons can now be banned, with approximately 2 weapons banned per map. This means that if you have cleared 3 maps, you should be able to ban 6 weapons. I am not sure if I have made the necessary changes or if this quantity is sufficient for everyone. If you feel the need to make changes, we can continue with the modifications. Gru, that goblin wearing a scarf! I have designed a minimum movement speed of 15 for a player, and I think there should be no problem. However, to be honest, I have never used this character to clear QwQ, so I am not sure if there are still any issues 4. Fleurie is a cute little one who can breathe fire! She can now exhale a full circle of dragon breath normally in double speed mode. I forgot if I updated anything else, I hope there are no bugs. Actually, I am still making a training ground and preparing to do some balance tests on the training ground, such as whether to change the damage type from 6 (cutting, impact, order, chaos, summoning, piercing) to 3 (physics, magic, mystery), and the monster refresh mechanism, etc. However, I did not expect this feature to be difficult to do. I have encountered many bugs and I don't know when it can be completed.Read full article on Community Announcements (StarMoon Cat星月猫)Patch NotesOfficial
