Turn off controller.

Replace

keys.isdown("up") ? {
keys.isdown("down") ? {
keys.isdown("left") ? {
keys.isdown("right") ? {} : {}
} : {
vel = [0, 0]
}
} : {
vel = [0, 0]
}
} : {
vel = [0, 0]
};

with

keys.isdown("up") ? {
vel = [0.0, 10.0]
} : {};
keys.isdown("down") ? {
vel = [0.0, -10.0]
} : {};
keys.isdown("left") ? {
vel = [-10.0, 0.0]
} : {};
keys.isdown("right") ? {
vel = [10.0, 0.0]
} : {};
keys.isdown("up") || keys.isdown("down") || keys.isdown("left") || keys.isdown("right") ? {} : {
vel = [0, 0]
};
math.vec.len(vel) < 0.2 ? {
collideSet = 2
} : {
collideSet = 3
};

A belated thank you, to you!
