I liked this game and it seems promising, but at the same time there are few things that i think can be improoved. I will focus on those things.
First, it can be fun for a while, but after a few hours is tiresome to be clicking on the item that the costumer wants and dragging it over him. It could be nice if the system were different, more agile, like maybe 2 different icons over the head of the customer and you just need to clic the right one, but having only a few seconds to do so, dunno, is just an idea, but the actual system become boring and tiresome after a while.
Also, the images that come up after using the "take out", "flirt" "care" and "give", i think they make the game very interesting, is something that makes you want to keep playing, but at the same time it would be better if always, or almost always the new unlocked images were the ones that pops up, so u dont have to try 3-4 times until you find the new one, and also, AND THIS IS VERY IMPORTANT TO ME, a stop botton or something that allows you to watch in detail the image, because they are very nice but is like "oh wow thats hot, let me see that... ey, wait! Where did that image go?? I WANTED TO SEE IT, FUCK DAMN IT! I know you could look for them in the gallery, but is not the same.
Also, it could be nice to unlock different and sexier dresses, not just summer and winter dresses, but thats less important in my opinion.
And lastly, a mini-animation while you are playing in cafe that reflects what the girls are suppose to be doing at that moment (like when they give a blowjob, titjob, etc, but you only see the image pop up, is not reflected in game) but i suppose this is harder to implement, and is less important as well.
Those are the most important things that can be improved in my opinion, but there are many other nice things and i think this game has great potential.
