Grimalkin: Solar Defense Force

Six thousand years into the future, the Evil Ancient Space Faring Empire has come to reclaim the Sol System — their ancient home world — from the Grimalkins, a race of sentient, space-faring mutated house cats with a fondness for 1980s aesthetics. Admiral Fluffy Duffy's fleet fought hard in the initial wave and their fate is unknown. All that stands between Earth and destruction is the Grimalkin Solar Defense Force and their Hyper Field Barriers. A tower defense strategy game about tactical retreats and defending the solar system with cats.
