Bienvenido a Fuwanovel! (No spanish anyone,seriously?)
Huuuuum,the only VN with comedy I can think about is Grisaia No Kajitsu,Little Busters,and MAYBE Shikkoku No Sharnoth (Most of the Visual Novels I read are way too serious,so meh......I need to re-check my tastes )
Can't say I reccomend Steins;Gates since,while at the end it gets better,the first part is boring because they explain you theories of Albert Einstein and rpqojprwqjrpwqj, which gets boring to the point that it forced me to hold CTRL (something I rarely do in Visual Novels unless I need to skip to play another route)
