Good start, although that title is already taken. (Mrytp is doing a series on the whole alphabet, starting from AAAAAA.)
I particularly liked the "Talky Terminal" sequence, and I thought "Broken Vridge" was a particularly cleverly-hidden trinket.
In the future, you might want to consider using Direct Mode, as it can be used to make 1-tile walls look much more polished. This is helpful if you want to keep using dense room layouts like the ones in this level.
