Wow, what a journey. Where to even begin? This is so polished - great music that fits so seamlessly with the progression and isn't too distracting, UI that's enjoyable to navigate, voice acting that is just superb, story that slowly unfolds as pieces of the puzzle of what happened fall into place. I was reminded a little of Slay the Princess, where repetition is not as it seems, and there's a play with memory... (Also, what does Alan Wake say? It's not a loop, it's a <spoiler>). I loved the characterisation of An Old Friend and the complex relationship with the PC; the mix of love and desire for ownership and control was so interesting to read in their behaviour. And I love that each ending has consequences, and how in some endings the consequence is kind of numbed if I step into an immortal character's perspective.
Congratulations to the team on completing this absolute gem of a visual novel, and in the span of a month! You wizards.
