Despite its short length, it manages to be a lot of things: confusing, off-putting, charming, funny and sad. The refusal to meet audience expectations (in this case, about both the English language and the form of a Twine game) creates a kind of vulnerability and openness that sets up well for the more serious content toward the end.
It's more mental work for the reader/player too, and sometimes that can be tiring, but in this case the game is literally about 5 minutes long and gets where it's going quite efficiently. Just use the back button with abandon.
