If saying that the puzzle you made is well thought-out and this is an objective fact is not praising yourself, then I don't know what is. But whatever, if it tastes nice, doesn't matter where it came from, right? I'm sorry that I hurt you developer's feelings.
And do you really expect people to specifically go into "more information" to find out this is a prototype for something larger? For a 5 minutes horror game? Really? Most of the people just view screenshots, read the description (some don't even do that) and press the download button.
