Proof-of-concept run for a fast route. Interestingly, no cat claws are necessary because of the Firepower cheat. No movement-related upgrades are necessary because of the Mobility cheat. This results in a run that skips most of the upgrades and key 4.

With faster earlier sections, Blocko can almost certainly be encountered one stalac rotation earlier (two seems less likely, but still within the realm of possibility. Three would require a major speedup and currently seems impossible.) Ultimately, Blocko functions similar to a SMB framerule for the first part of the run; faster earlier sections won't necessary guarantee faster times if Blocko can't be beaten earlier.

It's possible to get key 5 while holding left the whole time, but I was having trouble getting it consistently, and stopping for a second to jump over the checkpoint doesn't lose that much time. I also accidentally paused after Blocko (losing negligible time with the current RTA timing scheme).

This run is definitely beatable, but I'm happy with it.
