Hi! I've used this pack for the player ships in my game: https://eagleofbrittany.itch.io/starknight
It also has a steam page with a demo going live in September: https://store.steampowered.com/app/2462090/Star_Knight_Order_of_the_Vortex/
I've modified the ships slightly but they are still essentially the same. Thank you for the awesome sprites!
