Squidian The Bo Fish's video: Commodore 64 Platform Game: Cold Devil vertical scroll issue

Link for the PRG/D64/TAP file: https://www.dropbox.com/s/6kpvof26i4g7pah/Cold%20Devil%20v%200.2.zip?dl=0 This is coded in Assembly Language using C64 Studio. The graphics were also touched up using CharPad and SpritePad. So far Cold Devil walks, runs with an interesting "Shine Spark" visual effect, he has controlled height jumping and collision detection with the background. He is able to do an attack, but I am still working on the code to refine it. I also need to do further refining on the collision detection. Once those are done I can then work on a few "enemies" for him to slice up, and then on to getting the level to scroll around!
