I would swap in the UI the buttons, because the square button is on the right but it's z which is left on a QWERTY keyboard and same for button X which is x and it's on the right. Brain gets all messed up
Sorry to inform you, but I played a lot of Pico-8 games, and I believe is a problem of engine itself. Aparentally is the only controls that you can’t change when programming. I suggest to play with X and C, since C does the same work of Z.
Pushed a patch to be more consistent with player intentions and switched the guide to use C, will keep working on it though since it's still got a bit of friction.
