The next update (v0.21.0) will mainly feature a new mode: Contest

In each level, the well starts with a preset pattern which you must clear before you run out of pieces to use. Bonus pieces can be obtained by making “difficult” clears, using the same scoring system as Piece Trial.

The update will also fix some bugs that I found in the current version. I don’t have a set date on when it will be released yet, but stay tuned for updates.
