There is not much to this but it's not that horrible for a minigame. The female body drawing is typical overexaggerated anime style but that is ok, the animations are rather smooth and work well too, except for the walking - their feet are sliding on the ground as though they should go faster way too obviously. At least it's a stable game and obviously wasn't made too seriously. There is almost no gameplay, all you do is hold "->" to get close enough either to grap her intimate spots or come closer for rape. There is absolutely no "challenge" - the nun can't stop you in any way, only slow you down (while she can randomly approach you herself which is ironic and funny).
