Quick rundown of the controls (for the PC/Mac/Linux) version:
| Arrow Keys || character movement & menu navigation|
| A || Attack/talk/select in menus|
| B|| Open inventory menu/Back out of menus|
| G|| Dash (or "Go!") along corridors/swap spaces with NPCs|
| R || Rotate, i.e. allow direction change w/o using a turn. Hold it while using arrow keys.|
| D|| Restrict movement to diagonal (e.g. up+left arrows). Hold while using arrow keys.|
| F || Fire equipped slingshot pellets/use monster's special attack after changing into a monster.|
All the keys except the arrow movement keys are remappable to your liking, and Joy2Key
is reported to work for using a game controller. Here's a good start on mapping keys to a controller. Built in controller support is coming in the next update (Spring 2015)!
