So I made the update to the orientation, but have had trouble testing it, but I think its finally solved and the next update should fix that. The next update will only be a hotfix for that, although I might roll in one small fix, namely a smaller 6 floor tower, that is missing some of the more complicated enemies.
First Expansion:so the first expansion is going to be themed around fire. I already have added three enemies.
The Fire Imp: simple little monster, but will be summoned into levels, via portals so watch out.
Salamander: Will leave burning walls of flame in the spaces they have moved through, blocking off paths
Dragon Whelp: Similar to its older sibling, but only casts fire right in front of it.

The last guy is an idea I am toying with. After watching play throughs of
Crypt of the NecroDancer I am wondering if maybe I could design a boss fight. I want to add a new dungeon that's a volcano lair. It will be all fire themed enemies and instead of going in and then coming back out, the last level will be a boss fight, with king Magmar (name temp) he will attakc you and summon minions and you have to lure him into traps to damage him.
I am also thinking about adding a new enemy that is one of Magmar's General. He/she will give all fire guys on a level the ability to move three spaces instead of two spaces.
