The team is currently - due to copyright issues - moving away from the Digimon aspect of the game and will be using original monsters and concepts instead. It will still be DW1's spiritual successor, but without the digimon as to not upset copyright law. Check out our most recent posts for more info.
Currently particles can be put into the game by themselves and also put in along with characters and objects. More to come on this soon!
