No, I got some points. But I wasn't sure why I got the points, or what the water actually does.
Making a game self-explanatory is not easy, I aimed for that when making my first game here and realized that you really have to make things obvious the first time around in order for everyone to notice. What is obvious to you is NOT obvious to your players. Some will figure things out you didn't expect them to... others will completely miss something fundamental.
