Yeah, I remember playing a bunch of Our World is Ended, but never got around to finishing it. Not that it was bad or anything, it just got lost in my backlog of games over time.
The game was a lot better than I was expecting. The perverted dialogue was a bit much in the beginning, but as the game went on it became a natural thing and also pretty hilarious at times. Also, if you don't want to play this kind of content around others, the Switch version's portability really shines here.
Story also took an interesting turn halfway through and made things a lot more engaging. Also, I really like the art style of the game.
I'd recommend it unless you're not a fan of the occasional perverted humor. Plus, at that price it's even better. Especially if it has the mini-artbook.
