A very fun and very playable fan remake of Rescue on Fractalus
(aka Behind Jaggi Lines for some of us)
It’s been around/in development for quite some time, but only recently mentioned by @David himself.

It took me a few minutes to assign the joystick controls (they were all on joystick 0 instead of joystick 1 for some weird reason), but once that was done… WHOOOSH! Saving pilots and shooting saucers and turrets on an alien planet like it is 1984!
