Thank you for your support of the game. Based on player feedback, I have made some modifications to the demo version.
1-C
Opened the 1-C area, which includes a playable puzzle.
Puzzle Replay
Added a puzzle replay feature. Stand at the entrance of a completed puzzle and wait for a while to re-enter the puzzle. This feature can be turned off in the settings, and it is currently enabled by default.
2-B Puzzle Adjustment
For the confusing 2-B puzzle, I have added a tutorial level and adjusted the original puzzle. Note: After the update, the original puzzle will be in an unsolved state.
