Good life and death problems – Go Problems Review

Surprisingly good life and death problems for high-kyu level player. Solving problems raises your estimated kyu level as you go. Not sure yet if your session is saved, or whether you have to buy upgrade. No ads. I give it 4 stars because you cannot go back to previous problem, or I cannot figure out how to do that. Note you have to touch the text msg to see the full message.
