As the COVID-19 storms the globe, there are many efforts to battle it. This paper looks at the development of one such an effort in a form of a mobile game. The game is a 2D arcade game called Unus Terra. It is intended to be entertaining but aims to influence people to partake in social distancing through several mechanics. An early version of the game is evaluated by five usability and user experience experts using heuristics and a few other selected methods. In this paper, we present the results from these evaluations along with our findings from using this type of evaluation method. The use of heuristics is considered from the perspectives of academics and practitioners.
