I am a SMG2 modder, but I have trouble making really challenging levels. They just turn out way too easy. So I decided to make a NSMBW hack (aka limitless Mario Maker) for a change. My hack is 1 level long, but the level aims to be very challenging, with many sections and that lasts 999 seconds. The problem is, I want to require the player to carry shells and light blocks between zones, etc. To achieve this, I need to be able to walk from one zone to another, with no door/pipe. Is that possible?
Note: I am using vanilla NSMBW, not Newer. This is because I barely have space on my SD card and I want my friend to be able to play this without buying an SD card of his own.
If I made an SMO level editor, would you use it?
