Well, that was a fun game. Its strange, even though there is clearly many bugs, it is very palpable the amount of effort put in it. The immediate issues i see:
-upgrading shops, though they do seem to increase the income they generate, doesn't change their level number or have any clear indicator that it happened
-characters in the park with faulty textures
-Girl in clothes shop has blank eyes
-Player character's walk loop seems to be broken, after one cycle he just loops
-As of now, having the apartment deed, even fully furnished, does nothing(could at least let you nap and sleep on the bed)
-The apartment furniture stays in your inventory like consumables, and can be bought more than once for no reason???
-Finally, this is an issue that I'm not complaining about, since it made the grind much easier, but, though you have a limit on how many gifts you can give in a day, the gifts themselves (for example, chocolate), are not consumed. So I can give a girl the same chocolate multiple times, for easy Passion. I assume that is not intended, buuuuuut it did make getting everything easier.
And that's my report on this one. Overall, other than what was pointed out and a few grammatical issues, the game is fun and sexy as far as I am concerned. Keep up the good work.
