I think that the killer is Gelatin because he doesn't look all that suspicious and could easily kill someone without anybody noticing. But I also think it might be Suzume because we don't see her in any of the scenes before. Plus it couldn't have been me because I don't even like sports, besides Golf, Hockey, and Soccer. So I would rarely ever go into the Sports Closet for a bat.
1. I can't draw that well. Even if my life depended on it. So no, I didn't make this.
2. You almost got the whole puzzle correct and would've been 2nd but one piece isn't right. It has to be mirrored and rotated left. If you can fix it before I see anyone else's puzzle, 2nd place is yours.
