Hello reirrab and welcome to TASVideos. I was actually a bit excited when I saw this submission.
Curious how this compares to
Hardest Path...
I don't believe it's necessary to select
Time Attack when there should be a dedicated RAM Value allowing you to do fair comparisons to say the Hardest Path movie (I'll look into this later).
There's points on general bosses where you have questionable miss-shots; first, second and fourth
On the first boss, you hit an enemy on one of the drops, where theoretically you would've had enough distance to be able to hit the mothership one last time.
On the second boss, you unfortunately have shots that are missing entirely, where you could've in practice been able to shoot the enemy in the second wave... but there's another issue, the boss on this one can be beaten before it retreats the second time.
On the fourth boss, there's a questionable miss-shot.
On the final boss, when compared to FractalFusion you're allowing to be obstructed by the aliens, FractalFusion had to shoot one to get out of his way (and he had to deal with more cause hardest).
In comparison to the
Hardest Path you also don't play around enough in your downtime such as grabbing the extra points for no necessary reason, in my opinion this is what makes a SIE2 TAS unique.
This is a great start, but more can be done.
