Neat game
I think the balance could use some tweaking. I just bought turret slots and weapons, and upgrades. I never rotated my ship. I got through without ever feeling in danger and got to a "capped out" state of having every slot being a plasma lance + 1 shield + all upgrades. That is when I would hope the game would throw a final boss fight at me and then declare I win, either that or it needs an infinite progression system. It isn't much fun to wait for the enemies to slowly scale up while sitting on thousands of undependable resources. I got to 13:02 my problem isn't that its an infinite survival game (although I do personally prefer finite end goals), just that I capped out and didn't have much to do like 8 minutes before the end.
All that is to say, the game has a lot of cool elements, but I don't feel like they cohesively fit together into a tight experience yet. But good potential with some tuning.
Nonetheless, an impressive game jam entry.
