You tried it at all yet? I still think you dont need to know assembly to use C64 Dev Machine, just have a programming logical mindset. Needxa bitmap, drop a bitmap macro, need to move a sprite, drop a move macro, Need a sound effect, drop a siund effect macro, none of tgose require you to know assembly, but all options are there.
Give Lite a try, it might be all you need if you are avoiding code.
Cheers!
