Great game, I enjoyed it! Reminds me of echo chess, using the chess pieces for movement means it's really easy to pick up.

I noticed a potential bug (Firefox on Android) - I can pick up extra points by capturing, capturing again, then quickly moving back to the first capture square. I get the points as if it was another capture, even though there is no piece there anymore.

Edit: actually, I can quickly move back and forth for infinite points (and combo)

Huh, interesting. I guess it's because I remove pieces from the board with some timeout. Will fix.
