    I used to have this app on my Nook, and it's still great! I recommend this to anyone who likes text-based adventures. My favorite game is "Reverberations."

    This is not a bad interpreter, but it could use some polishing. There's no cover art support and sometimes pop up boxes (which Curses! makes extensive use of) remain on the screen when they should disappear.

    When will this be able to support Glux and by extension .gblorb stories? :)

    Love the stories. Wish some of them had a "help" feature. Otherwise, perfect. :)

    I don't know if it was just me but I couldn't make jfrotzs text big enough. this app has plenty of font size options and other customization and if this app had a scroll feature and a way to browse games without searching, like a list you could sort by top rated etc, it would be perfect. this app desparately needs a scroll feature though and autosave on story close would be amazing
