I gave an Original-Wait attempt and scored 95M. It probably could have been 100M, but I died to the final boss by misjudging my movement speed during a waitlag spike, killing my chain and thus my bonus on the boss' items, and also losing me 3M at the end-of-game stock bonus.
For reference, my current Original-Full Speed best is just under 60M, which was an odd run in that I wasn't focusing on score at the time, and that I haven't been able to beat it with a scoring mindset afterwards, but this is based on having played this today and never before then, so I'm still trying to figure things out.
Edit: Original-Full Speed, 81M and 1cc... except, I wasn't allowed to enter my name or save the replay? *sigh
