PunyInform

Also, a micro Inform6 compiler+library: https://github.com/johanberntsson/PunyInform Tristam Island as an example: https://github.com/hlabrand/tristam-island

Nowadays there's also PunyInform, an Inform 6 library that replaces the standard library. Programming for it is very similar, but the resulting games are much smaller and faster, to work well on 8-bit computers. https://github.com/johanberntsson/PunyInform There's currently a jam going on. Three PunyInform games have been released, and anyone can play and judge them at https://itch.io/jam/punyjam-2/entries . One of the games (Opportunity) comes with source code too, so you can see how it works, if you're interested.

Commercial parser? Hadean Lands and Anchorhead (the commercial edition) are just gblorb/glulx, a rehash of the Z-Machine with 32 bit capabilities. Said this, I'd like people knew Inform6 more, among IBG.pdf (Inform's Beginner Guide) and DM4.pdf (Inform6's manual). The language is dumb easy. It's object oriented (almost literally, you declare in-game objects as... objects with properties), and the games can be run on legacy machines fastly, such as Amiga/Atari/68k Macs. Here's an Inform6 libre game to start with: http://www.amirrorclear.net/flowers/game/devours/ Also, I forgot: There's Puny Inform, a reduced subset from Inform6 with few changes here and there in order to create games targetting the 3th version of the Z-machine. Thus, the games will run anywhere, even on the C64, Spectrum, MSX, BBC, Linux, OSX, Windows... everywhere. https:
