ahah yeah that's what happened to me too, I was covered in blood and I was like "wtf did I do ?" And I couldn't find the little guys anymore :') RIP
Sorry about that guys, I've tried to fix this glitch but have been unable to replicate it with 100% accuracy so I'm not too sure what's causing it. If you wanted to know how to get the final sunflower, it's on the top of the spider guy at the end. You have to hide in the tall grass and wait to pounce on him to try and pluck the flower. Anyway, thanks for playing my game and sorry about the inconvenience
