Ha, yeah, it's definitely a demanding one. There's certainly a knack to it, but it does require some self-training. I seem to remember the boss level at the end being tough even for me and I knew the patterns.
I appreciate you going at it for so long! I hope you enjoyed it despite the frustration.
I feel like I did install a skip level debug but I can't remember what it was. If I figure that out, I'll get back to you. :)
