Thanks for your detailed review! Polishing is my favorite part of game development, I had particles implemented before I even built the shop page lmao. I have to say you're giving me too much grace for the lack of music, I confess I just ran out of time to find or make anything fitting...
I'll see if I can fix the bugs you've described. Very fair criticism around the falling blocks and light mechanic. I didn't think too deeply on the incentives that the light mechanic would give the player, I was thinking more along the lines that it would be cool aesthetically and add a bit of tension around finding the exit. Thinking back on it now, the leniency around restarts breaks the light mechanic and causes it to work exactly how you describe. C'est la vie, lessons for next time.
