It's criminal that this dev doesn't have 4x the followers on Patreon. DAST has, hands down, the best natural dialogue and organic, believable narrative of all the drama-based erotic games on this site. With the work getting progressively better, I can imagine the narrative potentially standing up to some of Telltale Games best writing by the end of development, especially considering that early chapters might get a rework. That's a high bar though, so we'll have to wait and see. With the current 2.0 stand-alone build, the dev's also created (arguably) the hottest sex scene in a VN, though of course, mileage may vary depending on your whims.
As for renders, it's rare to find a Das3d game where the models' subtle facial expressions show real, emotional impact. Most games feature overwrought expressions and dead-fish cadaver eyes on porn-star clone faces, swimming downriver of uncanny valley, big fake tits in tow.
Though the early characters (Dr Amana, Japanese Co-Worker) occasionally fell victim to this dead-eye stare (as do virtually all Das3d games, DIK included), the developer has managed to leap past this hurdle with some stunning results, especially with the latest chapter featuring Cassie. It really feels as if there is something going on behind the eyes in these latest 2.0 renders, as well as in the later renders of build 1.1.5. Very hard to achieve in a render system like Das3D, but RomanHume has managed to do it very well.
Be warned, play version 1.1.5 first, which is available below the current 2.0 build. The old content will be modified, recoded and merged back in at a later date, but is currently separate from the new chapter due to a change-up in the dev team. The new content won't make sense without playing the old build first. Rest assured though, the quality keeps getting better and better, even if it's now a solo effort. This dev has got some real talent and puts an astounding amount of time and care into crafting this game.
