This game is so cool! Definitely an idea I've never seen before.
I love how you pushed the sand aesthetic into every aspect of the game, like the title text being made of sand. The cheers at the end of each level also game me nostalgic flash game vibes for some reason lol.
The level design is really interesting. Once you start controlling multiple blocks, some that only move diagonally and some that only move horizontal/vertical, it really forced me to slow down and challenge my usually instincts when controlling games. It was really refreshing! I also really like the level where you move the conveyor belt with you. It would be cool to see more of that.
One thing for gameplay is that it might be nice to show what percentage of the available sand is required to complete the level. That way, I know if I have to be careful not to let any sand fall or disappear, or if I have plenty of sand left over. I don't really know how to do this without cluttering or overloading the player with too much information, tho, unless you find a way to integrate it with the percentage bar that's already there.
It's really impressive how many levels you managed to make, especially with them all either introducing a new mechanic or spinning an introduced one in a novel way. Great job as always!
