Great concept! I love Recettear so I was immediately interested :)
The game works really well and looks great, and you also seem to handle fallbacks really well (the Player 2 servers were having difficulties I think while I was playing, but each time something failed it retried correctly and the game went on perfectly!)
My main issue would be the very frequent loading (especially since the server was slow right now), and a lot of those could be avoided I think:
- Main culprit was generating wares, with long loading after each click on a "?" item. But you could simply generate a few items in advance, and make them appear instantly on clicking, would feel a lot smoother! Then, you generate some more in the background when the stash is about to run out. Just this change would probably make the game a LOT faster!
- Less noticeable, but you could also gain some time by generating the next NPC in advance, so there's no loading when changing customer.
Alas, I can't think of a way to make the haggling's responses faster, but if the rest of the game is instant, that'd probably be less noticeable.
Haggling worked pretty well, if a bit random at times.
The "end of day" screen is really good and detailed, very motivating!
Overall, I'm very interested in this game, I hope you'll expend on it in the future! Great job.
PS. not a big deal but one font isn't working in the Auth screen (check the button at the bottom) :
