You can remap the Up Key for jumping in the Controls menu, though the reason we don't have it by default is because we use Up to aim upwards with guns (and it feels weird to hold both Up Arrow and Down Arrow together to drop through platforms). There's no shortcut key for restarting a level, but that's a good idea :)
