Exquisite. Divine perhaps. Really, really enjoyed these puzzles, super creative. I felt this tingle after solving them, especially the clock one <brain_explosion_meme>. The environment art and postproces was also really good, fitting the vibe. I managed to finish the game, but I had help from my gf puzzle maniac. So it was a glorious cooperation.
I really hope you will continue with this one forward, I feel that there is space for a holo themed puzzle game in this vibe. I would definitely re-play it in its final_final form.
My only "complain" would be that steps sound felt a little bit inconsistent which at first pointed me towards counting them. Their loudness also felt like a highlight that they are an important element. I would either ditch steps sound or make them repeat quite often and quietly so they don't stand out too much.
