2 Player keyboard controls

[TinAggit]

Hello I am also have a similar issue! I am trying to play with 2 people on the same keyboard. The first player buttons (WASD) all work. However, the second player (arrow keys) control button does not work (AKA my friend cannot cut anything up) but all the other controls work! Sometimes it works, but most of the time it doesn't. It's very frusturating because we love this game and want to play! Thank you for your attention and help.
