Thanks for all the feedback, Aside form the other 2 GWJs I did, I'm completely unfamiliar with exporting to web, but each of those worked right out the box. Thanks for all the tips though since I had no idea what to do to even begin fixing it.
The rotating issue seems to only exist in the web version for some reason as well, it probably has to do with the very odd way I coded it.
Only advice I can give for when you're doing too little damage is to just move around a lot first and build up momentum before attempting to attack, works for the slime as well if you go into that fight with a very high combo meter already he'll die in a couple of hits.
