Version 1.0

2023.1.23  PT

Update content：

The second part (24 new levels) has been added.

The difficulty of fixing the first part is a little easier than the previous version.

The difficulty curve is slightly flattened.

Developer's letter：

The update is much slower due to an unfortunate event at home on February 12, 2022.

Now there are 48 levels.

The third part will be updated in the future.
