Hey, I tried the update, and I can say I really, really like everything you've changed!
Aesthetically I really like the "map" feel, with the large skulls representing boss fights, the scrolling from area to area, etc.
I really like how the healer class now contributes a spell, I think it makes choosing characters much more difficult, which I like! (Although I didn't see if you modified the Adept, so I'm not sure if I would just take that class regardless of the spell that comes with it.)
All the new abilities and reworks of characters you did were very cool, and I never felt like anything was particularly weak.
I also like how a handful of combats now feature A LOT more enemies, so AoE is just intrinsically buffed from that.
All your new items are cool, I like every one I've seen so far, and there has been no confusion on what any of the new ones do (although that might just be because I played the last version 50+ times....) -and I really like the gamble for a random item.
One thing I used to be able to do, but cannot now, is swipe a selected die off of a character (before being done rolling, of course.) I checked the old version and realized that it wasn't swiping that was deselecting, but rather any mouse down event instantly deselected. Now, if you swipe up on the battlefield, you will no longer deselect the dice. Your mouse cursor has to stay on top of the character. I actually like the idea of left click selecting and deselecting more than swiping, just an observation.
Also, your .exe is called DiceDungeon still.
Oh, and I just started a run on Tough, and saw curses, and that is just awesome.
Really digging this update, and still can't wait for the final release!
