Oooh, I think i see what you're doing! I assume you're moving entirely in diagonal movements on the keyboard which isn't required for you to do
We should have made it more clear during the tutorial, but pressing "up "on the controller moves you north east, pressing "down" moves you south west, "left" moves you north west, and "right" moves you south east. On analogue sticks this isn't the case and you have to use it as you would perhaps expect.
Responding to people's comments we have got a build of the game where the camera is slightly off the isometric view, which would hopefully make it a bit more intuitive, but updating that during the game jam felt a little bit unfair, so we'll do that after the fact. The character not facing in the correct direction on entirely diagonal inputs on the other hand is a bug.
Thanks for the feedback!
