Thank you, i totally agree with the sentiment of inclusion and respecting the pronoun and genital preferences of all players! But unfortunately in the present day, video games are written by people in machine code, and considerations like these require more people, smarter people, and more complicated code. I promise i did try really hard!!
The game is open-source if you happen to remember some of the specific places where you got "he'd", or if you want to expand the game to include separate preferences for genitals/gender, expand the dialog choices, or even offer alternate more complex pronouns, or let the Pokemon themselves be non-binary. The possibilities are only limited by your free time, patience and technical expertise!

If you want to fix those dialogue typos, here are the two classes which include about 99% of Heracross's dialogue in the entire game (except for the places where they show up during other pokemon's puzzles.) If you remember the exact thing they said, you can just CTRL+F it and find it really quickly!
For example line 927 here, Heracross talks about abra and says "...if he..." and then line 950 includes the alternate female dialogue "...if she...". Maybe there are some mistakes or oversights! It's also possible you misread the dialogue, and they were talking about a male Pokemon in the game, but you thought they were talking about you instead. I'm not sure! Let me know if you find anything I should fix.
I'm sorry for your negative experiences with my game! Let me know if there's anything concrete I can do to remedy them.
