We're celebrating Nellie's birthday today, and this game is a present from myself and her community!
The puzzles were contributed by various community members, with the new 2.0 puzzles in the "Season 2" collection in game. New music was composed by the community's own Maxo, with Nellie herself unwittingly on harmonica! New in-game Nellie sprites were created by Tamagotaho, Aumchh, and Kindvirus (and the original DnDogge sprites are still included!)
Unfortunately the game won't be available to the general public until August 31st, which is the earliest Steam will allow a release (they require the store page be visible for a minimum of two weeks and I misunderstood the requirement, my bad!) but I'll be providing Nellie with a key so she can still play today.
We all hope she enjoys playing it as much as we enjoyed putting it together!
