ANTONBLAST Dynamite Demo: Part 2 - Boiler City High Score Run (452400 points)

This CAN be better, since i dropped the combo basically a screen away from the end I decided I had enough runs for today. Mayby a 456000-460000 score is possible, with full combo and everything collected?
Also, since they new demo slightly changed up the level layout, it's actually now good to go for all 3 discs and get an extra 1500 points. However, I still don't think going to the red room and back to the exit in time is viable.

CHEKPOINT BREAKING
WHAT A NUISANCE
The first two checkpoints have a bit of RNG to them to ensure that none of the chips get away from you offscreen or fall down the hole.
Not only that but Happy Hour is a big spike in difficulty for score too, those two rows of reds are hell to grab, and the last big batch has to be grabbed in such a way that you MUST get the first top layer when falling down, otherwise you miss out on points.
Im not doing Cinnamon Springs, or at least not putting this much effort as i did here.
