• It was unclear which actions the player should perform in order to gain

points in the game. Strange question marks and other moving objects were

confusing, and searching after hidden objects that gave points was

fruitless.

• It is not obvious what “enemies and dangers” the player should be aware

of in the game. What other characters and objects are really dangerous in

the game? What actions and objects should be avoided?

• The skateboard kid seemed somewhat dangerous, however it was not

clear at all how and in what ways he could harm the player’s character.

• Overall, feedback problems occurred in the game. When feedback was

expected (when different actions suggests feedback to be expected) it did

on many occasions not occur.

Empirical Usability Evaluations

• A lack of interest (from the test players) in reading initial instructions

results in frustration later in game when events, objectives and actions

become difficult to interpret and understand.

• Loss of only some game points as a result of an action was confused and

mixed up with a total loss of all points earned, which led to unnecessary

(and unmotivated by the game) disappointments among the test players.

• The music in the game is not connected to the actions taking place in the

game, which confuses players, as it does not highlight levels of danger

(which would be consistent with other games).

• The level of difficulty in playing the game is by many test players

experienced to be to low. The game is too easy and does not have an

increasing level of difficulty, which was expected by many test players.

• Test players reveal frustration over a lack of consistency with other arcade

games similar to this game, like for instance the possibility to jump on (and

“kill”) “bad guys” in order to gain points.

• The lack of possibility to move information pop-up windows, revealed

when questions concerning lasers are asked, frustrates the test players.

The pop-up windows prevent the players from reading additional information

placed in windows hidden by the pop-ups.

• Test players are frustrated over the fact that some objects, for instance a

plastic road cone, do not work/behave as in real life. In real life a road

cone could be pushed over, but in the game the player has to go around

the cone since the cone behaves more like a fixed object (similar to, for

instance, a fire post or a fence).
