Thanks for your feedback. First I have to say that every tester hast to play just one version of the game. Every version is equal in level, tasks, mechanics. Only the way the game “communicates” with the player is different. I guess there was a little misunderstanding.
About the survey … I know its a little bit tough, but I need all the information I can get.
I am very thankful for your help and I hope you had at least a little bit fun :).
