Alright, so I'm making a one (two actually) level hack called Yoshi's Eternal Challenge. It's meant to be a pretty long level.
The very first room of the level. Looks like there's something up ahead...
OH GOD RUN FOR IT!!
The first of three hub rooms. This is the beginning of it. You can flutter under the spikes but it's safer to use the shy guys from the pipe to break them away.
This is one of the areas that leads on from the first hub. It's quite small and it's about finding things in the breakable blocks.
Okay, now that I got the key from that first room I unlocked the door that you see on the far left. If I had a second key I could make some progress in that door. I have to use the helicopter to get into a small space somewhere.
Just hit a cloud to build a bridge. The cloud in the top right corner has a door which leads to two different areas: back to the start of the hub or to the second key if on the bridge.
...in a bit of a sticky situation here. This area also has Nipper Plants and Chomp Rocks.
This vine was in a cloud that a Chomp Rock activated. The cloud I'm pointing to is another vine.
This is the transition from the first hub to the second hub. It's an outdoor dark platforming area where you have to dodge enemies on your way.
The only way up is to bounce on the Flutter. Those two lines are pointless so I'll remove them.
Hub two is a tower area with mountains in the distance. I'll definitely change this.
I don't even know what I'm actually doing anymore... will I ever finish a hack?
