@Rich- I've come a long way since the old demos. Over the past couple of days I managed to recreate what was originally a month of work... and everything is smoother and more efficient.
Also... FLYING CRANE-STYLE DEMO UPDATE SPECIAL ATTACK!!

New things, and things not mentioned in the first post
Controls: Arrow keys, Space bar, Z, X, C
Pressing Z once will activate a light jab attack.
If you immediately hit Z again that light jab changes to a slower, but stronger punch with the other arm.
Pressing X once is used for interacting with things. Double-tapping X gets the cat to launch out of the armor. (you can 'interact' with the armor to get back inside)
Currently if you hold C you will walk instead of run, which will later be used for being sneaky and quiet (as an armored metal soldier cat can be). I might change how walking vs running is handled later to free up the C key for other functions though.
You can use Q and W to rotate the camera left and right, and the view will stop on convenient 45-degree increments... which is nice when you're trying to walk along a narrow ledge.
Pressing E will cycle through different vertical camera angles, to get a better view of things.
There's also a boss. It's based on the tank boss from the older demos, but works out a bit more smoothly now. It's not at all final but does currently have the usual features of a boss, like attacking, having boss music, the attacks are strong but avoidable if you're careful, and it can be defeated- causing victory music!
