Seems cool, though the autotarget mechanic is a feature disliked in many games.
It does actually do a decent job of diversifying the formula but I don't see a reason to replay levels such as studs and mini kits.
My other issues aren't so much with the game as the fact that it is from 2013. IMHO megablok hadn't crossed the quality margin than and many sets around that time were pretty much unplayable because of durability issues.
I absolutely realize any of this could have changed if the game was finished.
