Solid gameplay loop! There's plenty of polish that you could apply -- outlines on the font, CGs for the "how it went" cases -- but at its core, you've got a very solid concept here. Would love to see it explored. The twin genres of "sex toy building game" and "horny store simulator" are woefully underpopulated, so an entry that fits in both is quite valuable indeed :>
also that options screen gave me a giggle
