one of the best movement games here, shame graphics is too dull dark and few levels, and i wish it to give more points to grapple and dash to have even more fun :\
did you used any assets? if you made all yourself consider upload a movement system to unity store?
idea: if you combine grapple with dash in one input, there will be a room for shooter mechanic on LMB - (set Grapple and Dash on same button, RMB. if its fast click, it makes a DASH. if its held longer, it GRAPPLES from slower pull speed then dash, but accelerates to much higher speed if pull is long enough in time.)
