Over The Moon is something. It's definitely a game. And while its first impression is a bit like a swung baseball bat, it's solid and nuanced and I would hugely recommend it to anyone who's interested.
To start, Over The Moon has gorgeous layout and solid art. It also puts me vaguely in mind of Collectible Trading Moon Game, and from the wild premise to the individual beats, all of the jokes land.
Over The Moon is played over the course of a lunar cycle, between two people, using a messenger app. Your character sheets are dating profiles, and you play by messaging each other questions and responding to them. Both players respond with moon emojis, but the meaning of both players' emojis is decided secretly in advance, and you have to guess / decode each other's signs.
For how hard the game commits to the moon theme, it's extremely playable and clever, and it weirdly models dating pretty well---maybe apart from the moon stuff.
It also has an optional spicier set of questions, making the pdf maybe technically not pg-13, although these are optional rules and don't have to be a part of anyone's gameplay.
Overall, I would strongly recommend Over The Moon. It picks a gonzo concept, commits 100% to it, and generates something that's extremely playable in the end. If you like two player romance rpgs with a fun tone, or if you just like really impressive design, buy a copy.
