A downloadable game
This is a Ludum Dare entry. Still a low level prototype.
Defend invading aliens coming from a vortex created to transport them to your home planet. Destroy all of them, or you won't have a home to return to.
Just uploaded, for basic game mechanics play testing... send feedback to my Ludum Dare last post (Vortex Defender- dev #4) at: http://ludumdare.com/compo/author/r3igzyr/
