Having looked at the jam homepage it could use a good bit more information; even if someone was familiar with the game they could use some guidance.

Also the average person is lazy, the more they have to work to understand what is wanted, the less likely they are to play.
At minimul you might include a link to a descriptiion of the game e.g. https://en.wikipedia.org/wiki/S.T.A.L.K.E.R.

There seem to be atleast four main releases in the series (none of which strike me as particularly akin to MCs pseudo medieval fantasy theme) although the series does sound interesting and I recall reading Roadside Picnic.
