Overall pretty decent so far.
A few bugs to report:
-Early on in the game, there was a night where Prim asked to sleep in my bed. Then later on Yui showed up in my room and asked to sleep in my bed. The game did not seem to realize the plot hole in this and just ignored that Prim was already in my bed.
-When I go to the beach where Yui is (where you can train martial arts with her) if you are in the dialog menu with her and click 'back' it teleports you back to your room in the house rather than at the beach where you are.
-There is some kind of persistent bug with getting double charged, and/or not getting charged the right prices, for items in the store. The first million times I tried to buy a costume, it would charge me $400 or $500 but then after leaving the store, within a few clicks I would suddenly get hit with a second charge (causing my $ balance to actually go negative.) I kept reloading saves but it kept happening; reloaded to before making the purchase, played another day, tried going to the store again, same BS... eventually however I got around it. I have also noticed a couple of times buying things in the 'gift' store the prices listed are wrong (such as it says it costs $500 but you only get charged $400.)
-After progressing to the point where girls shower with you, if you randomly go to the bathroom and they are showering you still get the initial 'peep on them' options and dialog saying "oh if I was closer with her I could shower with her" ...even though you have already showered with them many times. I thought this was particularly funny with Maxy... it's like "oh if only we were closer maybe we could shower together" ... uhhh yeah she jerked me off in the shower a while ago, pretty sure we are close enough lol!
-Time does not advance from some events, or seems to but then suddenly reverts. For example, with the +Appeal events with Prim where she puts a mud mask (or whatever it is) on your face, time did not advance at all, it let me just do those back to back the same day in the same timeslot (I think it was noon) with no time passing. Another event, I forget which one, time seemed to advance but then when I went into another room it jumped back one time slot (the event had still been completed.)
