Ohhhh that makes perfect sense! I think I might be an outlier in this case. I use a Norwegian keyboard and our ASDF row have two extra letters so it pushes K and L further into the center, which leaves very little space for both my hands to be on the left side of the keyboard.
A lot of older PC games before we had reliable controller support always used arrow keys for movement and action keys were Centered somewhere around ASDF or ZXC. So I'd go with something similar as it will feel natural to anyone whos played a platformer with a keyboard before. But if you wanna keep the WASD movement, I think just using E to attack and Q for special attack would work fine. That or left and right mouse click.
Thanks for replying, cheers!
