The overall quality of the game is pretty hi, & pretty impressive for a “Captain America”(One man army). I should know as I am also Captain America. One major criticism I have, however, is the animations, which is not matching the quality to the rest of your work.
The motion is okay, but if you understand combat, & I have experience with it, having done unarm & rifle combat both in the military as well as Karate/Taekwondo, that it is not just about the motion, but the timing. If you can plot a graph of say a fist motion of a martial artist. the graph will not be smooth like a sine or delay curve. As the punching hand is pulled back, there will be a momentary pause.& as he swings his arm forward, the speed will be fairly constant, before a ‘jerk’ a fast acceleration of arm & body twist in the final 1/3.
You can test it yourself, Get in standing position, punch forward alternative between hand. Try swing as fast as possible from the moment you start the forward thrust motion. You will discover, no matter how fast you swing, something feels off, & the impact isn’t as high as expected.
Then try doing the same, but this time, at the final 1/3 of the way, give a huge grunt (breath out hard), & with all your might hit as fast as you can. You know you are doing it right if there is very sharp motion in your wrist, elbow, shoulder, & wist. That the ‘jerk’. The same principle for punching applies to weapons as well.
I provide video as a guide.
