Also, additional note for anyone using the February build, the controls
might be a bit botched. Either that or my controls fucked up somewhere within the downloading process. Either way, these are the controls as they should be, as listed in the controls menu.
(I should note though, X is not used for jump normally. Space is. But I find X to be far more comfortable and intuitive for me personally.)
(To that same end, it should also be noted that Shift is normally the button for masturbation, but I use E because, again, it feels better.)
To change your controls, press Settings --> Operation Settings --> Select Input Device --> Keyboard and Mouse, then click on any of the inputs listed to remap them.
