Fun mechanic! I liked figuring this out, really cool puzzler. I really didn’t like the pulsating effect, sorry it’s not for me. I’d prefer if I had an option to toggle it off. I liked that it was like the beat of the music visually, there’s something cool there. But it wasn’t my cup of tea.
Despite that, I still had loads of fun playing it. I really liked the challenges and felt accomplished reaching the next level. Awesome stuff :-)
