You can click to teleport the square to your mouse. If you drag in one direction, you can get (slightly buggy) physics in that direction! update 2: this could work as a space sim now... zero gravity added. BETA: gravity X. I'm not guaranteeing anything, but it could work if i decide to fix quicksand wall bug. I recommend using Turbowarp. You can find it at https://turbowarp.org/523727562?interpolate
@Thunder_Cat82Alt taught me how to make velocity based Y axis physics. All the rotation and X axis physics are by me.
