If 2.3 is ever released, here are a few bugs.
Setting the number of columns to one, clicking on a girl then clicking back makes the select screen have seven columns instead of one. Number in the column box remains '1'. Problem persists when switching sort method, but disappears when changing number of columns to two.
Sorting by canon, clicking on a girl, then clicking back makes the game crash to desktop.
Other than that, very cute, very nice 10/10 just enough water.
