This game is such a fun one to play! Controls feel nice, music is a BANGER, I am getting a crap load of Karlson vibes to this! I adore the fact that you can just shoot the AI at the beginning before it finishes talking like if you were saying "nah m8 ain't nobody got time for that" xD
The grappling hook is an awesome mechanic, though can be quite hard to hit while moving. Also, while wall running, my instinct was to hold diagonal to move forward and stay glued to the wall, but doing so slows you down. Making it so it ignores that left or right key while wall running (depending on the side of the wall) would help I think.
Apart from that, what an awesome and fun game to play and I'd definitely play a full version of this!
