Still alive and kicking, yep! Took an extended break from Terraria modding, as you probably guessed, but the recent announcement regarding tModLoader has brought me back! Dunno if anything will come to fruition, but I'm hopeful!
While I probably will ending up transferring the mod to one (or both) of the new modding API's, I'm not sure they've got currently got enough features to make it worthwhile. From what I know, they've just got the basics at the moment. When they're further developed, I'll take another look...
Whilst I think the scene in question was quite stupid, I think that making the particles do some damage is a good idea. After all, the Doctor does warn people to 'stay back' whenever regeneration energy starts appearing. I'll see what I can do.
