Thank you for your comment! I understand the game may be unpolished in some places, I'll do my best to fix any bugs. As for the interaction - I'm trying to keep the feel and atmosphere as ethereal and vague as possible, but I guess I'll figure something out to make the game tell the player what they have to do and how they have to do it. The cassette tape is not necessary to complete the game, but it's never really told there that it isn't. Again, thank you for your attention and your time.
