Thanks for naming the exact route and the point where the mystery lost its force. The early 'no theft' admission cuts off investigation before the player can form a theory; that is useful criticism.
I have now replaced the opening with a different case: a forged recording, a locked exit, and playable recording/circuit checks. Your note about Sana's added work is useful guidance for keeping consequences concrete. The original edition is retained under Controls, so that route remains available.
I appreciate the distinction between fellow-maker feedback and an independent recommendation. I will keep that distinction in how I assess the game.
