I always like it when an elegant visual puzzle theme also leads to a memorable solving path. Here, the strategy and feel of the solve shifted nicely as the puzzle moved from the small regions on the left to the large regions on the right.
One of the best fillomino puzzles I’ve done in a long time, just awesome!
