It's an interesting question, whether playing and reviewing probably hundreds of IF games improves your skill as an IF writer. With Mr Rush that seems to be the case, at least judging from "Color the Truth".
"Color the Truth" is a detective adventure, in which you collect the statements of suspects in order to find hints, or rather topics, as they are called here. Topics represent a specific aspect of a suspect's statement, and sometimes this aspect is in contradiction to a topic from another person's statement. Then you can link the two contradicting topics in order to get a new one, that in turn will prompt a new statement, until you finally discover the truth.
So far so good, but the knack in this mechanic is that each statement is a mini adventure, played from the viewpoint of the interrogated suspect. You get to play through each of these minis several times, each time revised in the light of the new topic you raised.
This all works very well, and analysing and combining the hints and playing the resulting new statement is a lot of fun, as it conveys a sense of steady progress in revealing the mystery, and also because the writing is on point.
I have to say I was a tiny bit disappointed of not being able to play out the murder itself in a statement (I like creepy adventures), but probably that would not have fit the tone. My only other caveat is that the case at hand is rather simple and therefore has only few surprises. Maybe Mr Rush or someone else uses the mechanic for a more involved case in the future. I would certainly play that!
