Well, here's my first Ghost House in my hack, called: Screamer's Crematory. Only the first part of the level is done, so I'll post some screenshots of the second area when I'm done.
Here's the screens:
The first area of the level remains a moving "Crematory". There's spikes underneath it, so, go look for a safe place.
Here's one of the safe places.
Some platforms have very little room, which is harder to land on.
Here's another small "Islands".
The rest is pretty straightforward. You just have to time the jumps on these little platforms.
At the end is a door that leads to the unfinished second room.
That's all for now.
