does anyone know what causes this glitch?

i made a slight move animation, which took me 1 or 2 days to make :)

some progress update featuring level icons, i think they look nice

simple addition, but its a good one

made bigger grid, fear it

this is one of the final levels in World 1

i made a stickman move on a grid, this took too long

made levels work, progress is good :)

a little tile game im working on

limit tile, which restricts movement
