So out of morbid curiosity I decided to drop the 25 USD on this guy's stuff and I almost immediately regretted it. I was right in my guess about it being a waste of time and money to download.
The only things that seem to have improved over time are the models whereas everything else seems to be a copy and paste of the same thing as the previous games. The game still has the worst move priority, shitty hitboxes, AND it has less fighters (16 + 2 boss characters vs. 7 characters) than the previous title in the series. I guess the "finishing moves" are a welcome addition, but everything else is utter ass and not worth the effort.
Not only that, but the other games they put out were also pretty bad as well. They use a somewhat different format, but it's the same thing just more zoomed in with somehow worse hitboxes.
All in all, I feel that the creator needs to focus on improving the functionality of their games instead of just removing and replacing fighters and calling it a new game. If they can't do that, they should probably just stick to making animations instead because their work outside of their mediocre videos is absolute crap.
