faster than 1 per day so have it over 10 by day 10?
Edit: thanks i got it. pushed hard this time to reach the checkpoint/classmate at day 0 already only shot the blue guys to advance to that point and ate the red lily u find after the big drop. was a bit tough to go for the dark red eyed enemies on day 1 already but managed to get em all (except for one on day 1 that fell off) on day 5 i already knew i was locked into ending B because of the color change. but DANG ending B bossfight is MUCH harder than ending A. ending A boss only need 20 bullets. ending B boss takes much less dmg and has much harder patterns.
had to change my rating for "Challenge" from 3 to 5....
