Report 02


We did two major rounds of playtesting. In the first round we took on 4 testers between the ages of 4 and 12 to test our game with their parent present. Play testers were given a pre and post test survey as well as debriefing questions during the session. The second round was the same but both children were 13 years old.


What we found from this was that the UI needed some further work as the players were not clear on how the abilities were affecting the game.
