I added a new enemy, a translucent worm with a ghostly trail, is the
equivalent of the Spectre.
I finished the pain state in which enemies can get stun for a brief
period of time.
Thanks to a member of the Unreal community I changed the way some sprites face the camera, now it looks the way other sprite-based shooters do, with sprites perpendicular to the camera horizontal.
I also changed the sprites of the Serpent and the way the system detects your screen resolutions.
Now I’ll finish the infighting system.
