That's some really great bookending you've done. First you started with calling it "really nice" before sliding in a subtle dig by dismissing it as "fun". After that you go into why it isn't very useful. Then you devalue it again with "fun" before wrapping it with a "cheers type" salutation(one that is careful not to send a message of quality only recognition of work done) before wrapping it all up with an exclamation point. Great work!
