With a trailer released just before Christmas, Eon is now available to play over at Newgrounds. It is indeed a take on Cypher Prime's Auditorium, with particle manipulation used to fill containers.

It's got a lovely feel to it, with the retro graphics and atmospheric soundtrack really doing it justice. I found it to be just a little too difficult from the get-go, but if you're looking for a challenge, this is it. There are even user-created levels (and the ability to create your own, obviously). Check it out.
