HEY! Someone else did a TAS of this fun little game. While watching I have a few questions:
vs Shademan: it's actually faster to use the medium charge-shot when he's just standing in front of you.
Vs everyone else: you did a nice job using the weapons you did. But why not the weakness weapons? They hit MUCH harder than anything else. Even over a charged shot.
Vs Pumpkin: did you test point-blank shots? It might be possbile to get multiple hits off of one blast if you're super close.
I know it's not the same, but perhaps my TAS of this game might be helpful to you:

I lost the .fba file ages ago, after I had put a lot of work into this only to get into endless debates about why this sitee doesn't accept these videos. You totally have my support on this one though!
