Nice Let's Play! Thanks mint301
I'm very happy to see that you understand everything I was going for.
To answer your issues:
The part where you fall down has a map at the beginning, but I've noticed that a lot of people miss it. So I must have made it too subtle. If you look at this map of the level
you can see how the the middle of the Premonition room relates to the rooms ahead. I did a few things to attempt to draw people's attention to the map (the room name, the lack of danger in the room, the matching background tiles), but it must not have been enough. I'm just an amateur, so a few mistakes are expected :)
Diagonal floors are great! I have some in my house.
I've only seen one person
complete room 8,7 with my intended solution, so I like that people have made their own path.
Several rooms use floating spikes, although they usually represent something (eyes, flames...) whereas the floating spikes in the room near the end don't represent anything, so I understand your dislike of those. I originally tried having platforms, but they took up a bit too much room and they interfered with the background art.
I wrote another campaign a long while back in my VVVVVV tribute game, called YYYYYY
. My campaign is called Fading Away.
