The big feature still missing is save and restore. (Undo works, however.) You can type “save”, and choose a save slot, and then type “restore”, and look through the saved games. However, restoring will always fail. (The data that gets written to the slot is meaningless.)
Other unimplemented features: sound, graphics, stylehints. (Also line input in grid windows, but I don’t think any games use that.) There is no iPhone/Android support.
It isn’t all that fast. Reliques of Tolti-Aph, in particular, has a miserably long startup time. There are some debugging lines and assertions that will be trimmed out in the final release, and I haven’t implemented the Glulx acceleration opcodes. But you can assume that anything which is slow now will be pretty slow in the future as well.
Both .ulx and .gblorb files will run from my hard drive and from the net, but without a status line window. I can also run Zarf’s quixe demos (e.g., parchment.html?story=http://eblong.com/zarf/glulx/quixe/demo/stories/Rover.gblorb.js ); they also do not have status lines. (Is multi-windowing broken, or is there just an issue with the CSS, say, for the status line?)
The 1 MB limit makes a lot of games inaccessible. Is that a limit that can/will be done away with?
Good work–this whole wing of endeavor is progressing beautifully.
