Thank you!
Actually, I'm also much more used to the left side of the keyboard but it's always a hassle for me to switch the layout because I'm on an azerty keyboard and our keys are ZQSD so I thought it would avoid this manipulation for the player and avoid having to handle the option to change the keymapping. I'll work on this for the next game jam.
As for the walk away thing, it's not a feature, it really is a bug :( I left it because I was short on time.
