On the negative side, there is a decent amount of game jam jank and unfinished stuff in basically every aspect, but that is to be expected with these things. I think the VN is ultimately more enjoyable than not, with the biggest thanks going to all the nice art and the smooth plotting.
As slice-of-life/romance, the game gains a lot from the vivid specificity with which the characters are sketched. I mean, the premise is a French forest ranger on vacation courting a radio host through their shared interest in retro tech – there's a lot of detail in there, and though I'm not familiar enough with all this stuff to speak for realism, all of it is described in an interesting, lifelike manner. It's also simply neat that there's a lot of different stuff happening. A lesser VN would be satisfied with using only one of the concepts explored here as its defining gimmick, but Wild Antler FM feels like a complete package due to its instinct to flesh out both the protagonist and the love interest and its sense of time & place.
Another excellent decision is writing the central romance as, essentially, a hookup. It's appropriate for the scope – there may not be enough words to work with for the characters to form a deep emotional connection in an organic way – and represents a welcome tendency to approach queer romance by gently pushing on genre boundaries. The fact that sex is a large part of what drives these characters to each other means that them getting it feels like a good conclusion, too, though the door is of course left open for their relationship to develop in other ways.
The story is all good, really; my only real complaints are editing issues with the prose, most notably many lines not reading like natural English, and some audiovisual stuff I think the team is already planning to address. The game felt like a pleasant read on the whole, and I'm saying this as someone who's not the biggest fan of the genre to begin with.
