I just decided to back up on kickstarter a spaceship combat game called Leviathan 3000. The author promises to deliver a simple and fun game, where the spaceships follow laws of phisics.
The game also have strong solo playability (author promises 8 solo missions).
With the print and play version set at only 5£ it can be interesting catch.
The kickstarter campaign is open till Friday, May 9th, and can be found here.
