One improvement to Veteran mode Sigma level would be to do allow the wall enemies on the initial climb to give guaranteed drops, much like in MMX. And if so, then respawn back to the beginning of the level instead of before the boss door when the player dies (although I can just walk back). Otherwise, those wall enemies are simply there to be a nuisance without any reward. It would be nice to have at least some type of health drop before walking in to refill. The fight sucks without Hadouken off the get go.
