Haha, the execution's pretty raw but I kind of fell in love with the concept. A unidirectional shield would be an awesome power up if this game was expanded, that's a great idea!
Thank you! I know it's a bit undercooked, but I figured a prototype of a game is better than no game at all. :)
I did try to tune the speed of the ship to be as fair as possible, but some issues cropped up. Bullets slower than the ship means a moving ship firing bullets collides with them right away. Haha.
So unfortunately, I had to run with bullets with 'unfair' speeds.
