Hello,
We're so glad you enjoyed the game!
While there isn't a sequel in the works, there is a remake with 3x the content that'll be released in a few months (http://store.steampowered.com/...). After that, there will also be some extra DLC episodes released for the remake, with one taking place before the game begins and two that take place after one of the endings. Depending on how well that specific release does, there may be more Blossoms games.
