It took me about 33 hours to finish, but other reviews claim 21-25 hours is the norm. I should have spent less time exploring the dungeons and skipped the final three seasonal dungeons once the way to the last boss opened up. The ending was brief, but quite happy. The kegare are disposed of forever, MC goes back to his world and has a happy end with his chosen girl (Femiruna). I was pretty satisfied.
As I said in the title, Conception is very enjoyable as a dating sim/visual novel, but as a dungeon crawler it stinks. A brief explanation follows.
Good dating sim
+ The character designs are really cute. The 3D close ups are not so cute, but they grow on you after a while.
+ With two exceptions (Mahiru and Ruka) the girls range from likeable to adorable. As romantic interests Tarua and Collette were a little too kiddy for my tastes, but everyone else was very passable. You’ve probably met all their types if you’ve watched even one high school anime before, but they’re well-done archetypes nevertheless.
+ Building a relationship is a low pressure, no failure affair. There are no bad ends, no jealousy events and no way to lock yourself out of a route. Even if you answer wrongly and piss the girl off, just keep talking to her week after week and you’ll eventually get her affection up. Do please go on, this is most interesting
