Amazing game. Completed everything except the four bonus levels. I might return in the future, but not right now. Its a bit quirky sometimes (where blocks end up after merging is a bit unclear to me still, though usually it doesn't matter).
The biggest "bad" thing for me was the sokoban parts. Where I had to sokoban instead of 2024 if you know what I mean. I enjoyed the math part of the game way more than trying to maneuver around. But this is most likely just a me thing. Some people might like the sokoban part more.
