Third Wheel is a fun project that expertly written and paced. From what I understand, Stinkdog is a long time Furry writer and their expertise is plain to see be it during the natural dialogue and the erotic moments.
Two points really stuck out to me, however. First and more important in my view, there's a certain lack of drama or any real conflict with these characters. Everything just goes pretty well regardless of your choices which I think saps a little of the potential this setup has to evoke some feels and explore these characters a little more.
The other thing I found lacking is the use of the "Id" character. In thought, it's a pretty nifty idea, offering a streamlined version of the inner voices of Disco Elysium. However, in execution, its presence never coalesces into anything tangible which I think gives the inclusion an almost gimmicky vibe. Things never come to a head, there's no paralyzing moment where the MC is torn between "logic" and Id; they occasionally trade insults and that's it. It's not enough to worsen the experience, but it did make me feel like something is lacking here.
Third Wheel may be a straightforward story where everything goes right but it's really well made one. I recommend for the craft alone, but it's also good for "playing single-handed" if you catch my drift.
