I don't know if this is intentional but it is very frustrating. For some reason every time cowboy goes for an attack in the air he seems to move backwards and if you have a long combo he starts going backwards at insane speeds. The only way to counter is to use teleport which will still keep the velocity you where travelling at, ending air combos to soon. If this glitch is happening to every body and not just me then it would ruin cowboy and make him the worst character. It just makes combat awkward and combos too hard.

Too make it short: Weird air glitch breaking cowboy.

I have a feelling that that's intentional. It usually happens in other fighting games too. When you're doing a combo that is so long, the guy getting comboed will move very when they get hit. It's one of the ways to prevent a combo that  can deplete the enemy's health from 100% to 0 in a single combo. Or at least to make it harder

It happens to all the classes I believe, each with their own circumstances. I sometimes drag Ninja combo out for so long that even "Store" momentum can't fully stop the speeds I go at after hitting my opponent. It's likely due to balance reasons which I don't mind. Makes prolonged combos a really interesting puzzle to solve.
