However, there is no way the tech can catch perosnnaly feeling in three days just for catchy pick up lines and binary (hot/codld) wireplay.
I also love this project, the concept is super cool and still very rare in games and novels. At least, this concept with a beleivable artificial intelligence is very very rare.
