I found this game overall to have a very compelling premise, but unfortunately it fell a little flat on the delivery. Overlooking the translation concerns (I can't even IMAGINE trying to make a full game in my second language, let alone in a 30 minute day time crunch!), the structure of the story is a little confusing with the newspaper articles and the bar scenes, something just isn't linking up for me and I think the pacing was also a little off because of those interludes.
I love the idea of finding clues, and once I realized talking to the detective was a pointless endeavor that led to only game overs, I was much more successful (though it was disappointing when I thought I'd found everything once and he determined that I hadn't, but that's on me).
I definitely had a good chuckle over the way the sprite hops over walls, rather than going through open door spaces on the maps.
One thing you might also want to do, is include a bit of a content warning at the start of your game. While it's true that they are just pixels in a made up story, some of the story elements and some of the graphics are a little much for the unsuspecting player.
I'd really like to see what this game looks like with some more polish! Nice work. :)
