I ported the Inform 6 version of 350p Adventure to PunyInform. No game content has been added or removed, and the player experience should be about 99% the same as when playing the Inform 6 version, except the PunyInform version should run at a decent speed on 8-bit computers.
You can get the z3 and z5 file, as well as the source code, at if-archive:
The game, and all of the resources above, have just been updated to Release 3, making use of PunyInform v6.0, and incorporating numerous new optimizations. The result is a story file of only 74 KB as z3, or 75.5 KB as z5, that plays really well on low-end 8-bit systems. Available for more platforms than you can shake a stick at.
