The only thing that separates Huniepop from the standard CG-collecting flash games that circulate internet is that it has voice acting and original art. For a game crowdfunded for 50k and making plenty in sales, I would have hoped for more than once scene introducing each girl, a few lines of generic 'what's your age/cup size' dialogue, and then 5 or more puzzle sequences to unlock 2 semi-erotic and 1 cumshot CG for each girl. This game is just another case of people getting way more out of crowdfunding than they would ever deserve for the product they intend to put out.
As far as the racism goes, I'm a bit desensitized to the tropes/stereotypes used when every girl has the voice of an Asian-American.
If you're gonna play it, I'd suggest immediately setting it to easy, unless you want to actually be challenged by the puzzle you're gonna be repeating 60+ times to get it with all the girls.
