Gave it a play. Very short so I'm not going to rate it at this point. Right now you meet the babysitter and you have a choice of three options: homework, watch a movie, or play hide and seek. You can do them in any order but can only do them once. Once you've done all of them you get a fourth option that kicks you to the main menu.
Homework is three questions, if you get them all right you can ask for a kiss on the lips, for her panties, or to see her tits. She'll always let you see her tits. You can only kiss her if you kissed her on the cheek when meeting her. You can only get her panties if you played hide and seek first.
The movie isn't really a mini-game, you just get to massage her feet and legs. If you got her panties earlier (requires hide and seek -> homework -> movie) then you can see her vagina and you get a message to wait for more content.
Hide and seek is pretty straightforward. She'll hide first in one of three locations. If you pick right then it's your turn to hide and you get an upskirt look as she's counting. If you pick wrong, you get another chance. Two successes (finding her and then hiding from her) or two failures (failing to find her twice or finding her and then failing to hide from her twice) ends the game but there doesn't seem to be any reward for two successes or for doing this before or after the other options.
The main downside is the engrish. It actually gets a little better after the intro but oh boy does it start bad from the noted overview gibberish to not being able to decide whether the main character's name is Simon, Saimon, or Jake. Capitalization is also very inconsistent throughout.
So that's what's there for now. I'll check back in after another version or two.
