Thank you for the insight! I swear I've been troubleshooting those black lines for 5 days and couldn't figure it out I'll take a closer look at the settings again and see what I can fix for a learning experience.
I just started a new project for a 2D top down 8-direction movement and it's working much better but I didn't have the sprites for 8-D movement in this game. I got some feedback saying I could use tweens but I haven't looked into them so I'm not sure how they work or if they would in this case.
Again, thanks for the feedback, I appreciate it immensely.
