Hi so I just played through the game for the first time and the insect scene is a pretty important one imo but there are only 2-3 cgs including art of it so if you focus on the text and not the art, I think you should be fine. But then again, I don't know you personally so just remember to treat yourself kindly and take breaks if you ever feel uncomfortable throughout the game.
Thank you! I'll try to focus on the text for my first playthrough, and then see if I can handle the art on a later playthrough. If I can't, I can just calm myself down with a blanket. I don't have a particular phobia of bugs, but seeing them just makes me feel itchy and nervous. Your comment really encouraged me to try it. ^^
