I think Lowglow is the one of the best casual games to come along in a long time. I really enjoyed playing it. I'd never heard of Elastrix before. It was released on Steam a year before Lowglow. I am surprised and a bit baffled that I can't find a single hit comparing the two games, on any search engine. Lowglow is definitely a visual improvement on the concept. And its soundtrack is great. But it is not as innovative as I previously thought.
