Really nice game! I like the aesthetics of the shop. The design of all the textures, assets and characters looks really good and well put together. The music fits well to the vibe.
I also like the various types of things that are being sold. Some unknown lot items, where you are basically gambling. People who are asking for a loan. Some people something specific and you sell them something else. It makes it feel less monotone.
It can get really frustrating when people keep offering you less money than you bought it for. Not in a negative way, but in a way that you are getting emotionally invested in the game. I like that!
I don't have anything to critique about the game, except that I wish that it had more content. More items, more upgradepaths, ...
Sadly I made a few bad deals and didn't win the game, but I really enjoyed playing :)
