One neat subtle bit of design that I love here is that it's a Sokoban-type puzzler in a sense, but the player is indistinguishable from the items they're pushing. When you yourself are an element to the solution (ie which "boulders" are placed where, and you're also one of those boulders), it adds an extra layer of depth to the puzzles.
Anyway, some levels are really clever, but some levels can be really chaotic in trying to predict what numbers will appear where. The latter feel less satisfying because they can be a bit "fiddle to win".
But overall I think the game is really clever and a great idea that I never would've thought of. It fuses Sokoban and Minesweeper together great and keeps both of their mechanics.
