Long Hidden Quest Completed

I took a break for two to three weeks in the middle and thought I wouldn't make it in time, but I played really seriously towards the end and finally completed it with only 7 days left! I think the rewards for this merge game are really well done. You can get a lot of rewards without spending money, and you can get stamina by watching ads. Later, I genuinely thought it was good and made a small purchase, but the rewards for watching ads drastically decreased! How outrageous, it's clearly punishing those who spend money... I haven't topped up since then.
