Here's the repo for the metaball effect.
Audio is more or less in at the moment; I've only started on graphics. Should be able to hack something passable together this week.
Nice job on the lava effect! I didn't know the technique was called "metaballs".
A detail is the red color made me think of blood more than lava. It reminded me of the elevator scene in The Shining ;)
Thanks. I should make it more orange. A glow effect would be nice too.
Graphics isn't my strong suit, having particular trouble with the second enemy at the moment. Trying to keep things simple and easy with partial success.
