Yo, this is a very interesting concept! I think you executed well on the atmosphere and art for this game. Well done! But of course, I have some other feedback about the puzzle design and also some general UX.

I’ll start from the spoiler-free one feedback first: It’s quite a nitpick to be honest, but when you rapid click the dialog, the voice will overlap. I think the voice for the previous dialog should be cancelled before the new one is played.

I also wish that the walking speed of the character can be faster lol. Maybe if you double click on the target location, the player speed can be doubled or something.

Now onto the feedback on the puzzle itself. I’ll try to talk in code to avoid spoiler, but just in case I’ll give a spoiler warning.

!!!!!!!!!!!!!! SPOILER ALERT! !!!!!!!!!!!!!!

There are three keys that the player needs to find. I think I found the hints for the first two keys accidentally, but it’s immediately obvious that it’s the correct answer. I found it by hovering on some elements as instructed by the bear. I personally think the experience is positive since I get the “surprised” and “aha” moment when I got it. BUT, I think the hint can be cheesed, for example by “inspecting the element”. I found the hint to one of the key by “inspecting” the sound related stuff without needing to know the piano and organ in the game (I still don’t know if the piano and organ are red herrings or not haha). I think a good way to fix this would be to “left” some information on the piano/organ. So knowing all the hints from the document wouldn’t tell the answer immediately without figuring out which one is the key.

Then, for the “right” key, I brute forced this lol, and I have no idea what’s the intended solution. The book on the right end seems like the correct direction, but I can’t find anything from there. Googling doesn’t help either.

That’s all from me. Let me know if the above feedback is confusing lol. Maybe we can talk further in the discord to avoid spoiler.
