^^^^The level is unfinished. Also we do not care about abbreviation conflicts anymore.
I had ideas of my own regarding two new rooms, not just one, where one replaces room 4
As for the angels they are staying, but will receive additional work to better flesh them out as a mechanic, such as new sprites and better code, while also better communicating what they do and how to avoid them. All said, none of this is planned for any upcoming release, especially not v0.3. We are currently prioritizing the main campaign, bonus content will come later
