If you attach your circle to a square that surrounds the platform your circle is sitting on, you can move it in any direction using this trick. If there is a platform directly below you, mark a pin on your circle, then draw a shape around your circle so that more of it is below you. Your circle will immediately clip through the platform
And the physics engine has some problems like I'd see in Garry's Mod.
Example
Funky stuff happens when there are lots of welds.
Similarly, I've found that this game exhibits weird behavior when lots of pinned connections are made. It can't seem to find equilibrium, and the whole structure keeps shaking like some fine imported booty.
Part interference also doesn't work consistently in this. I'll make a support shape, and then something hinged next to it, in the hopes that the hinged thing will rest on the support shape. Nope, the hinged thing swings right through it several times, before suddenly decided that the support shape is in fact solid.
And darn it, I want a more complex game. I'm trying to build a trebuchet, but it's kind of tough without any good way of anchoring anything to the ground, or any way of using things of variable weight, or without knowing how exactly a trebuchet works.
Update: I did it, I build a trebuchet to finish Level 20.
