The game is pretty easy. The murderer and the alibis are selected at random. (Spoiler - click to show)Only the murderer has no alibi, falsely claiming "I was in place X; character Y saw me there" but when you ask character Y, Y will say that they didn't see the murderer. You go outside, accuse one person, and the game ends.
I would have liked the puzzle to include a little more depth, something that gave me a sense of surprise (while still being solvable in hindsight).
I don't know why, but in Chrome 89 for macOS 11.2.3, the sound effects were horribly choppy. I switched to Safari 14 and it worked much better. It appears that opening this game (or any Strand game?) pins a CPU in Chrome.
The voices sounded computer generated, which was weird, but sometimes they really worked. I'd be curious to learn more about how the author made these sounds.
