First off, great job on your 3rd game ! Solid entry for a 48 hour jam. Minor points of improvement would be the use of better graphical elements (such as a custom font, textmesh pro), more animations to make it feel less slow and mostly an update to the AI algorithms. You could have multiple players swoop in trying to defeat you with different strategies, allowing the fleet to regrow to compensate for taken damage etc. Maybe add in a boss ship or two and BLAM , it'd be a great seller. I loved playing it, thank you for submitting it (under light peer pressure) to my twitch stream.
