Hey! Got here through your YT, fantastic progress in such a short time. The animation style is really fun.
My only criticism would be to change the camera control to something more standard (on keyboard and mouse, I didn't try controller). The mouse should control the character direction as well as WASD, pretty uncontrollable this way, at least for me. Check out the standard 3rd person controller in UE. Maybe it's just me, but I find it disconcerting for them to be separated like this. The MMB lock/reset makes it a bit more usable, but it feels like it's fixing a problem that shouldn't exist.
Oh, also - just a small thing, but adding some feedback to hits would be awesome. Right now the sword just travels through enemies and the only way you know you hit them or they you is the life bar. A little knock back/sound/impact animation fx would feel great.
Not sure how far you're going to push this, as we all know you could tweak and polish forever.
Love your work, keep it up!
