short dominoes don't limit flexibility of drawing pipe so that's alcazar, then with intersections(I'll call it T. don't bother rotating it until the end. just make sure there's not more than one side to wall or other invalid ~ since there's no 1-length rail to immediately put on nodes, so being adjacent to node would also disqualify a side. 3 of 4 sides open isn't that high a req on most maps) there's some even/odd counting of whether T should be placed on imaginary black or white grid, like in a three node situation, if u only have one adjuster, gotta use it for letting the odd one out adapt to T. then after u unlock wrench there's masyu making an appearance. classic puzzles galore. there are unique challenges but I'm not sure if they're intended... for example, starting night shift, try putting the short piece in last and see how it can't connect. also, are tutorial-ish bits for introducing new mechanics replayable? as in, each time u need to solve a few puzzles to unlock a box or smth -- I'm talking about those
