|System details||PunyInform games can be developed on any platform which the Inform 6 compiler can be built for. There are usually binaries available for Windows and macOS, but you should also be able to build the compiler for Linux, Amiga, Archimedes, Atari ST, BeOS, Mac Classic, OS/2, MS-DOS, Unix, VMS and EPOC.|

PunyInform is meant to be a lightweight alternative to the Inform 6 library, specifically for authors writing games for 8-bit platforms. Since games are compiled to Z-code, they can of course be played on more modern platforms as well. Compared to the Inform 6 library, PunyInform is more compact and has been developed with a greater focus on execution speed on slow platforms. Also, it can compile to z3 format.
From a programmer's point of view, PunyInform is very similar to the Inform 6 library. PunyInform lacks a few of the standard library's features, and some features are implemented in a different way to make for smaller and faster code. Some features are optional, so you can decide if your project needs them or if you'd rather save some space.

PunyInform can be used to build games in z3-, z5 or z8 format. All of these formats can be played on modern platforms. Games in z3-format can also be played on dozens of 8-bit and 16-bit platforms. Anyone looking to build a PunyInform game for as many platforms as possible should have a look at the Puddle BuildTools for PunyInform.
Comparison to the Inform 6 library
PunyInform has most of the features of the standard library, and the programming interface is very similar. Some of the most notable differences are:
- There is no Compass object and the twelve direction objects have been replaced by a single Directions object.
- Replacing library messages is done differently.
- PunyInform can not handle identical objects, like a pile of gold coins which can be split up into any number of smaller piles.
- The WriteListFrom routine doesn't exist, but there is a simpler replacement routine called PrintContents.
- A few of the library entry point routines used in the Inform 6 library are not supported by PunyInform.
- The set of verbs and the grammar tables for these verbs are not identical to what the Inform 6 library provides.
- PunyInform uses fewer objects than the Inform 6 library, which means the author can use more objects in a z3 game, where there's a hard limit of 255 objects.
