I love your game Cliff, and think it's super polished.....but I have to be honest, I've no love for this. Apart from a whole new thread for a very small feature, the glove makes no sense? Why is he wearing a boxing glove? Why that angle? Why no wrist? Personally, and this is just me maybe, but it comes off as a "quick hack" rather than a new feature to me.
I'd prefer it punched forward, maybe just a plain arm so it maintains that first person perspective. You'd already thrown about 5 punches before I worked out you were punching here, thought it was an icon on the screen.
