Most H-games feel impersonal and charmless to me. They often lack the sort of cohesiveness and/or passion that I think, for a game about niche fetishes, is more important to the experience than one might think. FOBS feels like it was made very spontaneously, as if the creator had too many ideas he wanted to get out and he simply had to make something in order to fulfill that need - and yet the game is still crafted with a sense of personability and consistency that makes it very endearing. This is one of the cutest game on this site, and it's rife with content.
The author, Zell23 seems to love making games, and he loves weird, cute monster girls to boot - I'm right there with them. One thing I appreciate is how 'monstrous' some of these monster girls get - there's nothing worse than a monster girl game that is too afraid to go all-in on the concept, not-so here. There are some really weird ideas presented between the 2 versions of the game (FOBS A & B), and even if not all monsters pique my particular interests, I'm glad they're there.
I really do appreciate the added layer of capturing monster girls, which brings a fun puzzle-element to the game. I would be lying if I said it wasn't often arbitrary how you go about capturing them, however.
The pixel art is simple, yet, to my surprise, manages to still be very expressible and sexy. Obviously, the game is sexy in a cute and conceptual-way, less-so in an intimate, realistic-sense, but if you were expecting HD ball sack textures and boob physics in this game, you're a maniac.
The art and music are both very charming - and I hate that a porn game makes me feel this way, but it really does come off as nostalgic and earnest in its execution. It's weird to say, I know, but it adds a lot of flavor to the experience.
I am very excited for the new FOBS versions too, and it seems to be steadily improving. He's almost done working on the fundamentals, which I hope means work will soon entirely be on populating the game with newly updated monster girls, with their slightly more resolute pixel graphics and better animations, and expanding the game environments.
This isn't the widest game, nor the deepest, but it's the most charming, and it's inherently cute. I find a lot of the concepts great for my particular tastes. I'd absolutely suggest giving it a play and supporting the Author.
