 Weekly maintenance updates:
 
+#2
+
+  * Fixed a bug where NG+5 difficulty would go down to NG+4 after looping
+  * Capped enemy movement speed after level 150
+  * Warden's bubble is now affected by magnify
+  * Changed all text instances of "active set" to "active class" to avoid confusion
+  * Added a run timer option - note that the timer will be off for saved runs that started before the patch
+  * Alt tabbing now automatically pauses the game while in the arena
+  * Shop level can now be reduced
+
