Xbox Live Indie Games developer Brooks Bishop (WastedBrilliance) has released Aeternum, a horizontally-scrolling bullet hell shooter featuring "cat-wrangling squids, corgis in spaceships, and hipster witches," among other bizarre enemies.

Aeternum boasts four levels and four difficulty modes, the hardest of which is described as "so hard even the creator can't beat it!" Jesse Bishop's chiptuney soundtrack is also available on YouTube and Bandcamp. It's catchy stuff!

Aeternum is priced at 80 Microsoft points ($1).
