Thank you for the constructive feedback. I didn't quite finish the game to what I all wanted. The death reset was one of the last things I added, and I needed to have it for a working game with less than an hour left lol (originally wanted health and knock back). Also, I never changed from the default font even though the resolution was so low, which made it blurry.
As for the parabola which I think you're talking about the throwing rock projection: I use a Line2D with repeating texture that has a characterbody2D that moves based on an input direction and speed, putting points for the line until it collides with the ground.
