Revised stages 1-2 to 1-4, and suddenly a huge improvement!
X360 Arcade
SPZ - 203,164,950 - 2-4 - Tiger Schwert
The highlight of the run by a long way was stage 2-3. I entered the stage with 0 lives and 1 bomb remaining, and cleared it with a spare life.

Needless to say, 2-4 wrecked me, but I'm happy to make it there for the first time and break 200m.
Will upload this replay to YouTube next week when I get access to my video recording stuff again.
EDIT:
Here it is.
