Growsim is moving along toward a beta release. Check out growsim.blogspot.com for more information on the latest build.
One of the new features that seems promising but needs more testing to guarantee stability is a plant-sharing system. Any cloned plant can be exported from the game; exporting generates a text code than can be copied and pasted into notepad or right into the Growsim game. Pasting this plant code into the game and importing it will add a clone to your inventory. This allows plant-sharing between anyone with the game and even between a single player's own saved games.
All of the major features are complete. Prior to a beta release, I need to get some testers to run through the game, particularly the new features, to try and catch any game-breaking bugs. So far, the few that have cropped up were easy fixes.
Thanks for reading.
