This is going to need it's own thread.
I'm about 30 minutes in, I completed the Boathouse/Tutorial section at which point I went through a Chinese gate looking thing that has another gate in front of it. I have 2 complete two types of puzzles. One where you have 2 different coloured lines hit the specific coloured pips. I'm on the last one of these and stuck. It's infuriating so I moved on and found another series of puzzles that seem to have something to do with the landscape behind them. I got to the third or fourth one of those before giving up, going back to the coloured lines and then giving up again.
It's great.
