Playing this is already quite satisfying, I can feel it scratching a fun domino itch of mine. Its refreshing to be encouraged to use everything also, instead of "use as little as possible" like many resource games.
Biggest feedback gameplay wise is tearing up a large chunk of your dominos to rearrange stuff is a tad clunky, but I imagine that would be mostly smoothed over by being able to click and drag while placing / removing, or rotating tools in place.
Good stuff, good job!
