Oh my gosh this game is so polished and elaborate with everything... Full narrative, stylish art, brilliant audio, intriguing mechanic. It truly amazed me and drew me in for its entirity!!
Maybe consider adding a small hint system, or maybe make detection slightly more lenient? I had trouble figuring out what exactly to enhance or scan, and wouldn't be able to do it without the walkthrough steps you provided.
But it's such an amazing piece of art! Looking forward to seeing this game in a larger scale on other platforms!!
