I’ve recently finished a remake of Spiritwrak, an old-school puzzler based on the Zork universe, which was originally released in 1996. It’s not 100% the same as the original, but it’s fairly close, so those who have played the original will find little new.
If you have never played the original but are familiar with Infocom’s Enchanter series, you are the perfect candidate! Please send an email address via private message here, and I will send you the pre-release version.
Be advised: This is not a comp-style short game. It will take a while to complete the whole game. Even if you are not able to complete it, your testing of early portions will be valuable.
