I never which key to put for the controls :-/
Except for the WASD, I struggle to choose.
Maybe the space was a better choice to throw. And which key will you choose for the jump ?
I have to say that when I played I didn't use the spacebar to jump, I only relied on dodging xD
So yeah sorry about that, maybe Q or E, or shift if you'd like to keep using the pinky finger, it's closer than the ctrl key !
Still, it's up to you and how you feel ! Maybe add an option menu where you let the players change the controls !
