Void: Corporation

In this AGT game (a parser that I find better than ADRIFT but not as good as Inform or TADS), you have to navigate an enemy stronghold using different cubes of software and slabs and pills.

It's not very polished at all, and the parser has some troubles, and the story has gaping plotholes (it's super easy to walk into enemy barracks and take things from soldiers). But it has a charm to it, and the story seems really deeply thought out; the author says they invented the world in their youth.
