Parser games let you type in whatever you want. They only respond to a small fragment of that. If I open a random parser game and say 'I endeavor to hop on my right foot fifty-five times before squawking like a parrot', then it won't respond with meaningful feedback (I know AI can respond, but the chance of that response containing content intended by the author that directly pertains to my command is low).

This is one reason new parser players struggle; how do you know what to type?

Parser games traditionally solve this in two ways. The first is by the community adopting unspoken customs about what commands are important. By experience, players come to know that 'X ME, 'INVENTORY', 'TAKE', 'DROP', 'PUSH', 'ENTER', etc. are generally understood and work well.

The second is by giving the commands in-game, either explicitly (like limited parser games that list the required vocab) or implicitly (if the game says, 'You feel a strong desire to yodel', then you can reasonably expect to be able to yodel).

This game takes neither of those two paths. In it, you play through various related scenarios about a traffic jam in an intersection. Many, if not most, of these scenarios are solved by commands that are both unusual in parser games and which aren't provided or mentioned in-game.

That makes this game pretty hard. Adding on to that, there are some default actions that don't have responses, making it hard to know what to do.

The storyline is a fun concept, and I enjoyed the ending, but I ended up using the walkthrough for about 70% of the game. I won't elaborate too much on the story as there are some early spoilers that give much of the flavor of the game, but suffice it to say that this is a puzzle about examining a system of interconnected events and trying to figure out how to adjust them in order to save yourself.

I think the game could benefit from responses to an ABOUT command to give expectations to the player. While I personally would have also liked more nudges in-game or a better idea of necessary commands, I realize that that may not match the author's vision and that they may have directly desired for players to have to hunt and experiment for a while. If that's the case, I think it's fine to leave it as-is.
