I'm about 1/4 through, based on map and item percentage. The game really opened up a bit after the first boss. I spent a good chunk of time exploring right and down, rather than up, which I think wasn't the "preferred" direction of exploration based on the number of dead ends I've encountered with my present set of abilities.

The relative lack of shortcuts is annoying (I'm assuming you've run into the non-elevator one?) but at least you're still able to grind money for upgrades running through rooms again.

Funny thing, I've invested most of my upgrades into the archer. With the critical hit and combo powers, she's very powerful and can hit things from across the room, which is very useful. I tore through one of the Black Knight encounters with her because of that.

I've focused on getting attack speed upgrades and the cheaper special abilities for all the characters. Not sure if that's the best thing to do. I haven't bought any of the non-character upgrade things as I'm not sure what they do. The game is intentionally a bit obtuse with the descriptions, so I'm not sure if those are permanent upgrades or things you're buying to temporarily juice up for your next run.
