This is fun, but if you reduce the tension and click a lot on it, it gets stuck with almost all the points at the top of the screen except one. Also weirdly in Firefox android it clicks a lot, not on chrome.
Thanks for the bug report, I definitely do see now that things fall apart at certain extreme values. I'll look into it and see if I can fix. My assumption is that it's some sort of numeric overflow or underflow resulting in NaN values, and that I'll probably just need to set the slider boundaries more carefully. Thanks again!
