Very polished and fun! The tutorial is great, I had no issues with understanding how to play, there are many different game mechanics, a lot of content and you even managed to add little descriptions for each item.
My only criticism is that I didn't really feel the impact of modifiers that you get for each inventory expansion. These modifiers are insignificant compared to late game items. I like the idea of 'cursed' items and taking risks. Maybe it would be fun if these bags didn't affect the player or enemies directly, but affected the items placed inside them?
Huge respect for finishing such a big project in just a month! Good luck with your future projects!
