[browser] [unknown, possibly early 2000s] 2D stickman semi-idle RPG with active physics; the characters had square heads and you could yank them around.

It was on its own website I'm pretty sure, and I'm pretty sure it was Japanese-developed although it was in english. Rediscovered it a while ago but I forgot what it was again... I think the name had "Stick" in it but couldn't find it for the life of me.

The characters were active ragdolls and white with hollow heads if that helps.
