This was the first game I made, so there are some stylistic inconsistencies here and there as I hadn't fully settled on how I was going to format certain things. I am aware of this though, and am fine leaving it as-is for now. For the most part, in contrast, GT should be much more consistent with things like name boxes (though I DO intentionally avoid dialog portraits during cutscenes sometimes, since the character is already on screen. No pressure, but if you do decide to try translation stuff, this kind of obsession with detail is exactly what I hope for for translators.
As far as the boar scene unlock, yes, that's intentional. It depends on personal judgement, but usually when designing the unlocks for the galleries I try to be a little "merciful." So yes, one boar defeat will unlock all of them in the gallery, but it won't unlock Diezel, or the other Diezel scene, etc.
