Ten operators participated in the study; each operator completed five different training scenes on three difficulty levels each.
Features of the demo included four playable songs on four difficulty levels for single player and co-op modes.
Every level can be played on three difficulty settings and several aspects, such as the enemies aggressiveness and the number of objectives that must be completed, among others, can vary in function of the chosen difficulty.
There are two difficulty levels, and depending on the difficulty selected, players can control one skycap or two at once.
This work also focuses on two technical difficulties when analyzing this type of data; (1) the reliability of gene expression profiles obtained from cDNA libraries and (2) the difficulty of using internal reference genes when working with egg and early developmental stages.
The tools are discussed and rated on four scales: difficulty of problems, complexity of problems, design phase and learning effort.
