I had to open Bronze first since i have not received Green. It was quite a shock to find out what changed from Blue when falling into the pool
But i don´t think solving Green would have me prepared for that either, so i think i´ll start playing with the Silver while attempt to solving Green.
I seriously want to open Green, but after all i´ve heard from, it is tremendously hard to do...after all Bronze gives you good feedback everytime you move on while i suspect Green not to.
But b2t, i´m eagerly awaiting the Silver arrival
