I'm pretty sure that you don't get access to A1's paint buckets until you leave A for the first time, but I included them anyways!

Thanks for taking the time!

I noticed something strange with all stages in A world's paint spawns; none of them spawned for me until i went to B world and then came back. I suppose we can't use A world paint spawns then :l
