This update removes some redundant and unnecessary elements, optimizes various puzzles and minigames, adds more detailed puzzle descriptions, and clarifies the story in certain sections. It is possible that these adjustments may lead to errors in existing save data. In these cases, restarting the current chapter should resolve the problem. 1. The early section where William must catch a number of robo-rats has seen a reduction in difficulty, and the goal has been made clearer; 2. The second act of "In Brank's Place" has been optimized to make the story clearer; 3. Re-optimized the second scene of the "Old Hydroelectric Station Zone" to clarify the objectives. The "Cellar Backroom" has been removed temporarily, and we will put it in a more appropriate position in later updates by means of a side quest. If you are working on this chapter, it is recommended to use "Chapter Selection - > Mistake or Trap? Uncovered Tracks" and then continue to play this level; 4. Optimized the third act of the "Square Street" case, if you are currently on this chapter it is recommended that you restart using "Chapter Selection - > We Meet Again, Whispers of Death!" 5. Optimized the third act of the "Smuggling Passageway", adjusting the use of the container crane to make it more user friendly. If you're working on this chapter, it's recommended to restart through "Chapter Selection - Left or Right? Making the Choice". 6. Optimized the third act of "Abandoned Dock", by removing and streamlining some puzzles so that the goal is clearer. If you are on this chapter, it is recommended to restart through "Phantom Echoes in the Records." 7. Multiple save slots added. By choosing "load", you can now select from up to 5 save slots; 8. Optimized some minigames, and removed some repetitive puzzles; 9. Rex has been working out and can now run faster than before; 10. Adding some minor NPC avatars; 11. The controller’s direction pad can now also be used; 12. Fixed various bugs; We continue to optimize and improve the experience, and the next update is expected for late June 2019. Thanks to everyone for the wonderful support!
