When you try to run it, errors should appear once it finishes attempting to compile (hit f6 to view them, f5 to compile). If there are none,, it should toss you directly into the interpreter, where you can type in commands. (It works perfectly fine with both NVDA and JAWS; I've tested it with both). I'm really not sure what you're looking for, but I can paste a part of a project I've been working on that demonstrates scenes (a little bit) and the power of dynamic descriptions.
***Begin pasted text***
A span is a number that varies. The span is 0.
Every turn, increase the span by 1.
Morning is a recurring scene. Morning begins when the span is 0. Morning ends when the span is 3.
Afternoon is a recurring scene. Afternoon begins when morning ends. Afternoon ends when the span is 6.
Evening is a recurring scene. Evening begins when afternoon ends. Evening ends when the span is 9.
Dusk is a recurring scene. Dusk begins when evening ends. Dusk ends when the span is 12.
Night is a recurring scene. Night begins when dusk ends. Night ends when the span is 15.
Twilight is a recurring scene. Twilight begins when night ends. Twilight ends when the span is 18.
When twilight ends:
now the span is 0.
When morning begins:
say "Hesitant light from the recently reborn sun heralds the start of a new spawn."
When afternoon begins:
say "Light from the planet's blue star becomes increasingly difficult to bare as it continues on a radiant arc across the sky."
When evening begins:
say "Light slowly drains from the area as the sun continues its journey clockwise, dropping below the rim of your humble abode."
When dusk begins:
say "Vestiges of blue die out in the eastern sky, signifying the spawnly death of the sun. The temperature drops quickly under the burgeoning presence of the moon."
When night begins:
say "The greenish grey moon gathers a quilt of star-stitched blackness about it, blanketing the world in night proper."
When twilight begins:
say "Greenish silver shifts subtly to the grey mists of twilight, which descend about your jar, but do not quite enter. Though illuminated by the moon, the natural satellite itself is no longer visible."
The Jar is a room. The description of the Jar is "White porcelain presents the soles of your feet with a surface slick and smooth as silicon, and curves upwards to form the walls of the chamber. [if the span is at most 2]Light, violet and pale, pours in from above, filling the room with the scent of dew and rotting leaves[else if the span is at least 3 and the span is at most 5]bluish gold afternoon light sizzles against the white ceramic as it gushes in through the open-air ceiling, leaving jagged black scorch marks across the pristine whiteness of the room[else if the span is at least 6 and the span is at most 8]Muted shades of blue and purple swirl peacefully within the heat-bleached confines of the cylindrical space, trickling in from above like celestial molasses[else if the span is at least 9 and the span is at most 11]Save the blinding spans near the middle of eachh spend, dusk tends to comprise the darkest spans of the spawn; there is no heat from the sun, nor cold from the moon, and your small home is plunged into a deep pool of terrestrial shadow. Specks of silver gather around the terrible black scars in the building's structure, signifying the start of the healing process[else if the span is at least 12 and the span is at most 14]The greenish grey light of a full moon accompanies the frosty bite of nightfall. Under its eerie glow, shadows shiver across the sun-scarred ceramic of the walls and floor, and the charcoal colored burns gradually scab over in gleaming streaks of silver[else if the span is at least 15 and the span is at most 17]Silver steadily drips from the walls of the cylinder. It gathers as dust on the floor, and is quietly lost to the greens and greys of twilight. Outside, the moon is only just barely visible; soon it will be no longer[end if]."

Truthfully I don't really use scenes for much here (what I do use them for can be easily replicated with the spans system probably) but I use them for something later, so that's why they're there. This does, however, demonstrate how to make a proper room, with descriptions that change. I decided to put an example of that because the grammar required to set up some of the variations in text and put math into words can sometimes get tricky and annoying.
Inform is designed to make text based (and so, by definition, fully accessible games). It is accessible, down to the compiler and the tester. I am by no means an expert on inform, but I've read the manual and probably at least have sort of an idea of what I'm doing.
Anyway, if you have any more questions, let me know. I hope this helps.
Go, balloons. I don't see anything happening. Go, balloons. Go, balloons. Go, balloons. Stand by, confetti. Keep coming, balloons. More balloons. Bring them. Balloons, balloons, balloons! More balloons. Tons of them. Bring them down. Let them all come. No confetti. No confetti yet. No confetti. All right. Go, balloons.
