Hello!
I finished chapter 1 recently. I managed to do it without relying on Mate and without hacking. It took a very, very long time - but it felt great to finally overcome the challenge!
My strategy was to get good enough in the first two phases so as to not get hit at all, and hope that I somehow survive the third. I'll be honest, I can't even see safe spots in the third phase most of the time.
I would love to try going for not taking damage, but it feels so hopeless. Could you possibly give a video demonstration?
I really enjoy your game, I'm looking forward to the rest!
