Thank you for your input.
We are aware of the possibility of rolling through a wall however it (should) happen very rarely.
As for input the game was aimed to be played by the members of the Game Jam. Within our group everyone uses AZERTY so keybinds and rebinds were not a priority for us.
I agree as for the use of the mouse, i too personally would prefer keyboard only but a group vote lead to leaving the attacks on mouse.
