Action Quest

I underestimated this quest ㅠ After reaching Mine 7 yesterday in a single day, I thought I could finish the remaining 7 mines today! But... it took over 180 minutes to reach just one Mine 8 ㅠ It's going to take even longer the further I go... I was tempted by the reward of 40,000 gems to try... Did it take me a long time because I don't have the knack for it? If only there was enough time, I wouldn't have given up and would have reached each one... I guess giving up is the answer ㅠ
