I'd like to post my thoughts here on the game here as well.
I really enjoy the new graphics, for one. It's like you've added more wit to a witty game.
While the gameplay isn't that much different from the original, the additions you've made (sub-dungeons, preparations, etc.) are very helpful and spice up the game a bit.
The difficulty levels! While I immediately skipped to the hard levels after seeing that the first boss I had to fight was level 5, the hard dungeons seemed challenging. Anoobis, for one, took me a while to figure out. I thought it was going to be easy UNTIL I REALIZED HE TURNED INTO A ZOMBIE. AND THEN INTO A SHADE.
Absolutely great new mechanics. I like them a lot.
What I don't particularly like is the interface of the kingdom, or the dungeon selection for that matter. When I first saw the town in that first preview picture you guys put up, I thought it would be one of those "CLICK THIS BUILDING TO DO X." Perhaps it's just for demo purposes, but whatever. Choosing your race and class seem particularly awkward, since they're just on top of greyed out kingdom boxes. I hope this is just for the demo and gets fixed in the full release.
And while I do like the dungeon variety in the demo, I think that the dungeon that has every monster and any boss would be in order. For old time's sake.
I really like where the game is going, though. I'll get around to purchasing it when I have enough e-moneys. Original until then for me.
