The Blue Rose steam version finally has a release date!
Barring no issues, Blue Rose will finally release on Steam on April 23rd 2015. That is, in less than a week!
The steam release will contain an updated script, a few corrected event CGs, as well as achievements and trading cards. Those who have already bought the game directly through the White Cat website will receive keys following release for activation on Steam itself.
The game on White Cat’s own website will of course also be updated to reflect the changes and improvements in the steam version, though there will be no achievements or trading cards.
Hi no Yabu 
Hi there! I bought Blue Rose awhile back, and recently got Steam. How do I go about getting a Steam key? Thank you!
Hello! That depends on where you bought the game. The White Cat website and most bundles will already have steam keys available for you.
If you bought the game from Desura or a Indieroyale bundle, there might be issues however. In that case send me an email with proof of purchase, and I might be able to help you out: http://www.the-white-cat.com/?page_id=190
So I went back to the order email to show my proof of purchase, and my Steam key was in the email! I guess I didn’t pay attention before since I didn’t have Steam. Oops! Thanks for your help! 🙂
No problem, glad it worked out 🙂
