What can I say that everyone already did?
My friends and me only dreamed with this only in our young days, and watched a lot of hacked cartridges here and there. but this!!! this is a whole other story!!
The only weord thing I found was World 6-3 about 3/4 of the stage with Simon some of the blocks won't break with anything or jumps when hitted below.
Aside from that I'm playing my more pleasant game in my life
Way to go!
