I'm trying to get all the achievements, and some seem to be broken. Living superball, The Conscientious Lagomorph, and Follow the grey brick road don't seem to work with the bunny.
The conscientious lagomorph might be my own fault though, if I'm touching tiles that I didn't notice.
However, the other two either can't be done with the bunny, or are completely broken.
I'm sorry for such a negative comment :(
I think the living superball achievement is broken. I thought you could do it with the bunny, but maybe not, because I did it without pressing the jump button and using the bunny and I didn't get the achievement.
I don't know if there's any other way to get it, if there is please tell me what character.
Thank you for your time.
