It was mostly the broken text to go along with (what I'm assuming) is their broken English(?). It's very charming and cute but sometimes it would take me longer than it should've to actually understand what the character was saying.
I can get a screenshot of an example later! I'm not very good at explaining with words </3
Other than my personal gripes with the text, everything else in the game is really good!! I didn't notice any bugs :D
