Thank you, Kobato! I encountered this same bug in the browser version (on firefox) and again after I downloaded it and played it on PC. It's a relief to know what was causing it... (The first time I encountered it in the office and since all the magnifying glasses don't light up right away I associated it with that and not pressing "talk").
Anyway! Thank you Puchi for making this game! u__u I'm playing it right after finishing Silver Thread. I love your sprite art and the way you did the backgrounds in this game is really cool! :3
