My prayers have been answered! I have wanted this to be ported for so long and it has finally been done. And you have kept the shortcuts which make it so unique. Great job.
As someone who has played the track well around one to two hundred times in my life… THIS IS AMAZING!! My nostalgia kicked in!! But… the rail shortcut in my opinion is just too good, have a good mach bike or even bullet bike and you can clear the shortcut too easily… I think making it Star or Mega Shroom exclusive would balance it out. I’m not an expert, but it would make the track feel healthier since it would be trapped 24/7 with FIBs, bananas, or the occasional bob-omb.
that wall at the end has the koopa cape ending waterfall collision on it, so going on there without a power item will just push you off and make you lose a ton of speed, it requires a star, mega, TC or 2 shrooms (in my small amount of testing i couldnt get it with a single shroom but i wasnt thorough with it)
