ero ge. Lovers. Actually it's koibito no somethingseomsething. Produced and published by Jelly Fish. Good 3d. Pretty boring plot. A few funny jokes. Best part is a gag reference to Ayu (kanon). While picking up girls the protagnist and his buddy hit on this girl with a backpack (batwinged), and she is eating some awful bean curd thing.
Been a long time since I played that though, and my japanese was even worse than now.
Just find a gamecg torrent. The animation is okay, but the voice acting and plot isn't really worth it.
Koi ni Ochitara. I have this game sitting on my harddrive, haven't touched it, but I guess this might be a good opportunity for me to measure your opinion. Jellyfish is alive again, by the way, after a few years(?). They've got two new games and one remake in their lineup now. Now that makes a grand total of... 5.
There are two games like this, "Love Escalator" and "Lovers"
"Love Escalator" was released in the late 90's by the company Jelly Fish. It featured three characters, this character having the most CG out of all three of them combined. The animation wasn't top notch though, considering the graphics.
"Lovers" was released a few years later with this same character, by the same company I believe. With much better production.
It's really easy to tell when you look at the animation differences in the two.
