I guess I'll try to do it again while recording. And yeah, the key is to avoid triggering your boss attack at all costs. :derp:
Yeah you can really cheese the game by not playing it the way you're supposed to play it.Tried a run out of curiosity, and while it's not as hard as I remember it being (probably something to do with it being a year since I last played it lol) it's still pretty hard. Got Yumemi down to half a hearth, 59 million no cheesing.
There're still a bit of stupid luck involved though, especially in the later levels. If the AI sends a boss when you just happen to have no bombs or charge you're pretty much fucked if they keep throwing their impossible to dodge attacks.
I once dodged everything for 5 minutes straight without getting hit and then died within 10 seconds.
It's not so much an issue with boss Chiyuri as your charge recharges so fast because of the tons of shit going on, but Yumemi especially.
