Neat concept but I would have liked to see something on your page explaining how the game fits the theme. I think you were going for something along the lines of scaling your business or economies of scale but I wasn't really able to tell. The idea of balancing what you spend and what you make is a cool idea. A little more graphics and music would have helped as well. That said, there was something just fun about watching the numbers go up and occasionally catching a funny log entry.

This is an interesting idea for a game. Watching the adventurers do their thing reminded me a bit of Dwarf Fortress, how each dwarf has their back story and there is a log of what they have done.

In some instances, I was unable to read the logs so fast and at the end of the day, the logs would disappear immediately. I also think that the game would greatly benefit from having some tutorials as it seems that the mechanics could be pretty intricate.

Honestly you have a really great idea here. I wish parts of it were explained better (I.e. where the things I buy go to, that ending the day early means you're literally shutting down the whole day without money). A random generator for little facts about the heroes could be fun too. Develop a little attachment. I also am unclear whether the items for various slots are just ranked by their tier or if they have differences. The magic greatsword and axe have wildly different prices besides being in the same tier, but on the adventurer list, it's just listed by the item's tier. Anyways, it's a good idea. You should definitely expand on it.
