Oooh yea that's a good stategy, I didn't think of doing it but it's actually a good counter against stone-19! It does make the fight much easier.
Also I played the rest https://www.twitch.tv/omshinwa/videos?filter=archives&sort=time though I think i kinda abused on the -77 lol. Aw you changed the layout of fight 97? I liked the challenge because it seemed like the last stone to get. It kinda forced you to use stone 23 etc,
Love the game as always!
