While the game itself is both simple and interesting, I noticed a few areas that could be improved. The fact that Koyama can insta-lock on to you even at long distances is imo the biggest thing to me.I would suggest giving a "grace period" of how long it takes her to notice you are out of the trash bin. General fps/game play optimization would be nice. Beyond that, game has a nice atmosphere.
