Game has a really brutal difficulty curve but is quite fun to deal with once you get used to it as long as it sticks to the roadblocks and the regular sword enemies in sync. Anything beyond that and my poor hands just get decimated. I can't react fast enough haha. Definitely could've used some more smoothing out in terms of difficulty!
Also I'm not sure if this is accurate or not but I feel like there is a very minute lag in swapping chars right after performing an action. When enemies are tightly packed together this can be a very deadly occurrence.
