Kusoge Girl Wattery is a unique and humorous collection-style exploration game that compiles about 30 mini "kusoge", roughly 20 previously released by the author and 10 new ones created specifically for this title.

At the beginning, only a few games are accessible. By playing through them and earning trophies, more games and areas gradually unlock. The trophies vary in type and difficulty, adding a layer of progression and strategy to the otherwise chaotic and comedic presentation.
