For 47, there are 3 part that I was struggling (maybe others too)
47
The first one is to lift the block off the ground
Hint
Push green up with red
The second one is get the block off the spike
Hint
Push with red, and green need to catch the block fall 1 square so red can go safely
The third one is get all snek to portal
Hint
Red need to fall from right most column, so create hook with green so red can push green left
