At this point, every web game I try starts with testing for one specific bug - if you right click while moving, does it screw up the movement so that you are still moving after you let up on WASD.

Yup. It does.

It is a cute idea. But the implementation is flawed.

And if the goal is to help people explore cultural artifacts, building a game that actually minimizes the importance of the artifacts, and literally just drives the player to squash them up into a great big ball might not be the best way to help people actually appreciate the items.
