Interesting
I have to say, this wasn't that good. The concepts behind the sketches were sound, but the execution was flawed. The only part that I liked was Rina-chan, and that was spoiled by a hidden message.
In the middle of the screen, there is a sign that says "RTIL IS A HMO". You need to look really close to see it, but it's there. It sort of soiled the experience for me.
