Absolutely! Merka’s insecurities are a big part of his route, especially since his love theme centers on philia, and he’s the hero associated with envy. For example, you can see the 'hero' thematics play out in his interactions with Rosario, where they show off their wings. Additionally, his height complex can make him get pretty fussy + when others treat him like a brat—which fits right in with philia’s need for friendship or brotherly love.
Yulen, on the other hand, is much more direct. His love theme of mania drives him to pursue what he wants with an intense focus, which can make him a little extreme, especially as the hero of wrath. Unlike Shyloh’s clinginess, Yulen’s approach is about total commitment—mind, body, and soul. And when it comes to things beyond his control, like height, he might use others (like Merka) as a teasing point to feel just a touch superior/competitive. (Could the pixie's height hint at something deeper? Just a clue for you!)
Are they the most violent of all? Hmmm... I can think of two possible characters who maaaay be more intense but... that would be super spoiler territory LOL
On the production side, life can definitely throw a few unexpected twists our way, but we’re in good shape! Most art/music assets are ready, and now we’re focused on script edits and programming.
And for Rosario, as the hero of lust, his shapeshifting ability allows his anatomy to switch between coiling and standing parallel (hemipenes are still there XD). In the bad ending, we went with the coiling option to keep things simple. For those choosing female or intersex anatomy, there will also be a prompt during said NSFW scenes to select options like anal or vaginal, so players can tailor the experience!
