WIP of an attempt to max out the score counter as fast as possible. Redid almost all of the first stage from scratch with a much better route. Currently ends on the last frame of the 3rd All Clear animation before the game starts taking input again. The AI will get KO'ed about 12 seconds later regardless of any subsequent input and award a massive stage bonus (542.4M if no further input, can probably be increased slightly with a counterattack or two).
Next steps: Figure out the optimal number of times to advance the seed before the next stage starts, then repeat. 3 All Clears and a 13 combo should be enough to counterstop.
