Yea, tutorials are the worst : ) to a large extend, I believe that games should not have one (and my plan is to remove the one in Bunny Bunker) as they typically are just annoying, and its lazy to do as a designer.
I would not be to afraid of giving to much away ;) I would approach it differently.. how much is needed for you to collect the right amount of data to improve the entire game. As soon as you have it done, you can change and charge money for it. Get data to improve game for higher profit is my logic. Better game = more revenue.
The monster was a bit confusing.. but I think mostly it was because I was unable to kill it.. and it did not kill me.. so I ended is some sort of limbo state. That to me was the biggest problem.
