It was pretty fun :) ^ Ofcourse it is nonsense - exactly as was aimed for - it is silly comedy and thin excuses for ecchi images of girls. But that isn't bad if done well enough. The characters seem ok - they remind me of Kyouko, Yui and Akari from Yuru yuri a bit.
The art is also very nice and some of the images were pretty erotic. I helps that it is all colour.
Sure it's not gonna break any ground or be some deep story, but I don't mind silly lighthearted yuri either - especially if you throw in a bit of fan service - and it stays all colour.
