Oh, hm, it seems to be working fine for me and the people I've sent it to. It sounds like you may be encountering a permissions issue? Twine (or maybe just the Sugarcube framework I'm using) saves to local memory for things like settings and save files, so if something prevents Twine from doing that, it could cause a storage error. Maybe check your plug-ins or cookies settings?
Could you paste the exact error for me? I'm nearly positive the error isn't specific to my game, but I can do a quick check.
Edit: I took a quick look around, and yeah, the most likely culprit is that you're blocking cookies. If you'd like, try allowing cookies for this page and see if that fixes the issue!
