I played this a couple of years ago, but eventually lost interest. The game starts out interesting, before being bogged down by the cumbersome gameplay of the RPGM engine. There's absolutely no reason why this game couldn't have been made on Ren'Py.
In terms of the story, it's pretty cliched - the only difference is that the wife's descent is initiated by a magical necklace instead of marital boredom. The issue is that things escalate so quickly, with every single character she encounters, that it becomes laughable.
You've got your sad-sack cuck of a husband, the lecherous "best" friend, the powerful boss, a seemingly endless array of hobos, and of course, the BBC element that's so prevalent in this genre. If you're looking for a quick fap, there are other VNs you could spend your time on.
