I feel like I should have a webpage I can link to every time I leave a comment, which says something like "When I spot a flaw in a game that a studio spent two years developing, that's on them. When I observe a weakness in a game that one person made under a one-week game-jam time limit, I'm doing so with the understand that, OMG, you made a game in a week! That's awesome! And I liked it and I'm not leaving a comment to try to make a bad thing good, but to help make a good thing better. Really, I'm only saying anything in case you feel like you have the time and energy to return to it!"
In all seriousness, this was a very good puzzle game. (Also, now that I think about the one-week limit, I realize, "Oh, all those games about doors--this was one of those, wasn't it? It's just that it incorporated the behind-the-door theme so well--central to the game, but not central to every move you make in it--that I didn't notice.") Think about the feedback as much or as little as you like!
