Game submitted! Hopefully all goes well and we can release this week.

The name is meant to be a contrast from the cartoonish look, energetic music and general upbeat feel of the game. We toyed with other names like "Happy Violent Space Friends" but thought that Space Murder was most effective. The "Revenge of Mace Spurder" part is kind of an inside joke. One working title for Gravitanks was "Tank Frenzy: The Revenge of Frank Tenzy", so it continues the theme.
