|W6, S4, S5 all have a barrier gone now, after getting the spray can from E3's blue treasure..|
then the blue treasure from S5 was a pair of scissors, made the balloon go up in the air in S6..
a drill destroyed the floor blocking the wind in E6..
got binoculars... a door appeared in N6
found a gong... it somehow made the sun appear in S6...
pickaxe opened a portal on E6...
and now I have no leads left for the last 5 treasures...
this game is SO tedious near the end... to do this without a guide you'd need to be really diligent with taking notes... even moreso than I was already.
