I'd meant to do more with this blog for Spring Thing, but ShuffleComp testing has taken up a lot of my time & I've enjoyed looking at what people did. There are still a few days left, though if you have seen this blog, you probably know about this link.
So I'll have to settle for mentioning a few e-texts I've been enjoying: Who Killed Harlowe Thrombey in e-text. It's probably one of the best CYoAs out there, and definitely the most ambitious--a detective story with relatively good internal consistency for a CYoA, but disappointingly hard to find in local libraries compared to others. The structure is unusual for a CYoA and it even goes left to right instead of jumping around. Best, you won't spoil things or get exasperated flipping through it due to the neat GUI.
Other books I poked at include Richmal Crompton's Just William and (for all the wrong reasons) Amanda McKitrick Ros's Irene Iddsleigh which is impossible to read in one sitting because...err.
