SCORE 102, I challenge you all.
Le Slo! Again, absolute best of the genre! Very elegant minimalism. Beautiful game-design, theme is awesome!
I feel the mechanics are just perfect for enraging mistakes, so I see almost no reason not to include UNDO (exc for infinite regret cycle, but limit to 3 and solved)! For better scoring, maybe eliminating some randomness is beneficial, I'm trying to figure out lvl of randomness at the moment...
Personally, I also find dynamics pretty monotonous after a few games: the process consists of minute improvements in heuristics, no memorable moments, like executing a long plan to create some valuable element. But I totally see how brittle established balance is and the number of elements is just right to keep it all in mind. But some really rare elements which you crave maybe ok, the problem will be strategic streamlining, though.
"Be the passage of time" - this is just ingenious. CONGRATULATIONS. (We need to solve your popularity, though!)
