v 1.2.0 Added achievements, balance adjustments

- Added 70 achievements
- Advance the timing of 'action' increase in battle as much as the number of monsters killed
- Lowered the conditions for success in mining part-time jobs
- Highlighting the line that 'gut' is necessary when working part-time in the mine
- Fixed an error in English spelling of duck numbering in the ending

Originally, there were 170 challenges, but there was a limit on the number of challenges, so I could only put 100. However, I belatedly add the 70 challenges that were missing because the restrictions were lifted by satisfying conditions such as sales. Thanks to all users :D
Other than that, I've slightly lowered the difficulty of parts that beginners may have difficulty with.

Recently, I am working on a Japanese translation of 'Lullaby Days' and developing my next work 'Candied Loveache'.
The days are getting colder, everyone, be careful not to catch a cold.
