Hyper x cloud 2, its not realty that the sound is broken or something it just kind of unpleasant, especially having to hear it so often.
Maybe its just preference but if i had to describe it id say its the sharp start to it and the square wave sound it has (i have absolutely no idea how sound works but the jump sound definitely feels not great for me).
Controlls:
Maybe spread over more buttons; movement with wasd / arrows and special actions on xcv/bnm
Where jump is x, stomp is c and v+ direction is slide. Would need some testing, to see if stop on s and jump on w would make sense.
something like that
but thats just my feedback, ultimately its your choice if you think my complaining is valid :D
