Apologies if this is already mentioned, but starting to use a spell (doesn't matter which) I am not able to undo it. In the alpha you could click again on the BURNDARAYZ icon and it was undone.
Not being able to use return or enter when text crops up is a bit annoying too.
There is no sound to the frazzling particle shower when you kill off a boss. Would be nice with different sounds for different bosses too of course but that's a request.
Lord Gobb is an extremely wordy fellow.

PISORF does not work if the enemy is backed up against the outer edge of the dungeon, if there is no apparent wall. Zombies get killed off very easily at lower levels (me being a lvl 3 halfling can kill a lvl 4 zombie outright with one PISORF spell).
