very polished cute small puzzle game to spend time with, its a standard sudoku like game imo, it fits the theme to "unblocking" the flow for a solo game dev you did a great job.
some feedback i could give is:
-the character cuteness might need some improvement
-the puzzle needs more addition imo like 2 plungerman or events or something it could be better
but overall its a good game! perfect for advanced category.
