Datsuburo!
Platform: Java
Publisher: Nanashi no Rakugaki-jo
Game: Block-breaking
Difficulty: 3
Nudity: 4
Caveats: Lolicon

A series of breakout games using the B2 Java applet. This circle releases new editions every year with girls from anime series released during that year, in games which you use a block-breaking game to knock off their clothes. We’re not going to list every single release since it would be kind of redundant, but these screenshots were taken from Datsuburo! Act 4.

This series was formerly available on DLsite, but has since been removed.
