I suppose I shall submit a monster, in an attempt to secure a copy of this amazing-looking game. What I am envisioning is not (necessarily) a horrible grotesque creature, so I shall say that it falls under the gigantic category (sometimes) These are basically variable-size blob creatures that could have different body types i.e. have wings. Be friendly, aggressive, or even be in a sort of limbo between the two. Behaviour: Some may have basic instinct-based intelligence, hopping, flying, or digging about. Some may have that surpassing the most intelligent of humanoid creatures, controlling vast mechanical armies. Some may also fade in and out of existence, as if being phase-shifted into this universe. Generally towards each other they are non hostile. Their attacks could vary from smashing the player, to firing some kind of biomechanical death beam. Habitat: They could inhabit strange, alien worlds, perhaps some kind of amorphous gel world, building complex civilizations on them. (or destroying them) They could have emotions reflecting their behaviour: Evil (robot-ish) blob! Although my retextured sprite does not do this idea justice, I believe it could be a great addition to the game. Note: They do not really have to look at all like what I sprited, my spriting ability is rather third-rate, I was aiming to make a blob of goo as interesting as I could.
That's cool, but I think your idea too general a concept. I know that it's supposed to be (since they're amorphous jelly things), but you may want to tighten your focus a little.
Well, they are pretty broad, but generally only inhabit those jelly worlds, have a relatively similar appearance, and will likely have some form of special drop. Either related to their type, the same for all of them, or both.
