Alright, I've watched it. It's definitely not bad for a first TAS, but there are a few suboptimal parts:
- Wall jumping up vertical shafts seemed slow in general. I'm pretty sure X could wall jump faster.
- You didn't use dashed uncharged shots + fully charged shots against the intro boss (unlike FractalFusion's run), which I'm pretty sure is faster.
- It may just be me, but I think there are more places you could abuse ice superspeed than you did.
- On Blizzard Buffalo's boss battle, you didn't move away from him to shoot the uncharged shot faster and thus charge faster.
- I noticed a few places where you dash down a pit, rather than dashjump prior to falling down, so you fall down faster. I'm not entirely sure, but I believe that is faster here.
- You beat Toxic Seahorse in three rounds of Frost Shield rapid fire, the published run in two.
- I noticed you dashing on conveyor belts that move against you, slowing you down. I'm pretty sure dashjumping over then is faster.
Also, the category is rather trivial. I recommend you don't submit it, as it would most likely be rejected. Feel free to post the run in the Mega Man X3 thread, though.
