I've just played through the game, ran through most of the content. Overall I'd give it 2~3/5. since there's no .5 stars leaving it as 3. It's not a terrible game, far from it, and has a lot of room to improve but...
I have a sort of checklist for games. Nothing long, just three criteria:
1) Doesn't drag on (whether from need to grind, travel, unskippable text, etc.)
2) Has good porn
3) Has an interesting story
If a game has two of these I tend to consider it good. So even if it drags, as long as it has great porn and an interesting story I'll still play. If the porn isn't great but the story is and it doesn't drag much, will play. If the story is crap but the porn is decent and it doesn't drag much? play.
Sadly, I can't say Dandy Boy excels in any of the criteria
The story? Mostly isn't there yet, and what we have isn't all that interesting.
The porn? Mediocre, and highly limited. It being action 2D instead of more Daz is nice, but the artstyle doesn't make up for mostly meager pickings and lack of anything particularly hot.
Finally, the game very much drags between travel, searching, and minigames (albeit they were only necessary all of 2(?) times). To an extent the creator has to have noticed some of this given the bus stations acting as a form of fasttravel within town, but it's still a drag.
tldr; game isn't terrible but isn't good yet either.
