I loved this a lot! But in the post-game endless mode, I got stuck trying to combine dusk dendron and brimstone to make the next plant - I always get an empty sacrifice result. I wondered if the dusk dendron was inactive unless I harvested it after dusk, but I could never get that to work, since by the time it's dusk, it's too dark to see to harvest it! Don't know what I should do. :(
