I will take these things into consideration!
When you are talking about the gradient and glow, are you referring to the stroke / edges of the sprites? And like some offset area around the sprite edges themselves? I did have post processing effects, but I removed them though, in hopes to get better performance on the browser (like bloom). The difficulty ramp definitely needs some work. I need more player feedback before I figure out what to adjust. I feel like I was trying to balance it with ship integrity, restoration drops, and the use of the Barrel Roll.
Appreciate the feedback, thanks for playing!! ✌️
