I was really turned off by how there was no sound in this. I will admit that the graphics are fairly decent. Another problem I have is that it's a bit hard to get used to. It seemed like you were looking for something that was big and this did fit the bill. You have to pay attention to absolutely everything going on here. I can actually see this becoming better.
I should judge it fairly as it is a demo. Then again, demos are kind of frowned upon on this website. It had a pretty funny title too. You might want to put in a couple of enemies, but then again, it is pretty hard on its own. I like how the liquids move.
