I played the latest version and while it's improved, it doesn't fully fix the gameplay issues in my opinion. Movement is better but it's still not great. It's a little bit more controllable, but also just slower, and I'm still having problems jumping onto things, grabbing overhead bars and climbing. It does feel less bouncy, which is good, but I'm still having a lot of trouble trying to move precisely.
My playthrough was also cut short by jumping through the ceiling and out of the map.
I appreciate the fullscreen toggle for playability's sake but unfortunately the game does not look good in fullscreen. I think it's still rendering at 720p, and stretched over a 27" 4K monitor it's blurry with indistinct lines. When blown up a lot of the flaws in the graphics that I hadn't really noticed before stand out.
Combat feels pretty much the same to be honest. Maybe it has less knockback?
I noticed the hints for the controls show a SNES controller with Nintendo button layout. I looked at the original version and it was the case there are well. While this looks cool, I think the majority of players will be using an Xbox controller or at least something with the Microsoft button layout so it may end up confusing.
I think you're moving in the right direction with this but it's still not there.
