...so, unfortunately, this game manages to hit two different pet peeves of mine: first, when making an archive (like a zip file), as a courtesy to your users, make sure that it creates its own directory (with all of its files) upon unpacking, as otherwise blindly unpacking will fill up your current working directory with files that are then annoying to sort out. Second, a lot of modern RPGMaker games do this, but invisible barriers at the edge of the map are pretty annoying. Being able to see the directions from which one can exit a room is very important, although in this game there are not enough areas that it was very frustrating.
In any case, I feel like making this type of mystery game in a game jam is pretty ambitious, and I feel that it could have benefited from more time: more puzzles, a more intricate plot, etc. I think it does get across the idea of what it was going for. While the focus mode was a bit frustrating to use, I think most of the issue was from technical limitations: a way to turn it on without going into the menu and an indication that it was on (instead of a message when it turned off) would have gone a long way.
