This was very very cool. Loved the personality of the robot and the conversations it had between the different objects on the sea floor. The use of the CSS editor, the music, and the art were fantastic. This was really fun to play!
On my first playthrough I eventually got to a point where it appeared I couldn't proceed without decontaminating my friends on the ocean floor (when I intended to not do so). Not sure if that is a bug or not but just thought I'd mention it.
Really great work team! Awesome stuff.
