Hi! Thanks for the compliments, I appreciate them :> And, yes, obviously, thank you for the bug reports. There was relatively little playtesting done, so things like these are just bound to happen, haha. I’ll take a look-see soon to see if I can replicate ’em and what I can do about ’em.
As for the puzzle, I’m assuming you’re referring to the piano puzzle, I know that many players seem to be having problems with it, so I will most likely be patching in a better clue/hint with the aforementioned bug fixes. Unfortunately, I haven’t written any guides for the demo, but I can tell you that there’s an alternate ending if you’re willing to do a little experimentation with items and characters, so feel free to give it a try (wink wonk)!
Hope you have a good day!
