Ben Hickling has been hard at work on his new Star Fox inspired retro arcade shooter, EX-Zodiac. The game is about to do a Kickstarter campaign, but before that, you can download and play a demo version right now, for free, thanks to the Steam Game Festival. Check out the game page for the details. Some time later, the full game will go into Early Access, where you can play the game as it is being developed.
I was able to get it and play it just now. It plays very smooth and seems very polished so far. The demo only contains the first level, however I was not able to get past the first level anyway because I only have access to keyboard controls. The game is clearly better suited to a traditional controller, though you can certainly play it with keyboard controls and even remap all the buttons. But put a controller in my hand and I can tell that I would feel right at home. Give the demo a try!
