I mean, having actually played what's available for free, and being a transwoman myself, both the player character and the lead femboy are sensitive about trans people in a way that indicates the writer being familiar with the topic.
The currently only available scene with the transwoman in the game isn't the same dynamic as the other characters.
None of it strikes me as phobic or even misinformed, I can't really tell you not to find it distasteful if you do but I think it's disingenuous to imply that it comes from malice.
