When I tried to play, every time I released a dragged piece, it shook back and forth more and more vigorously until leaving the screen altogether.
Thank you. Just looked at my code and it seems like that could happen when fps is below 20. Very easy to fix but didn't run into it during development. New version that should fix this issue is up on the page now. Will find a way to test if the game functions as intended at low fps for future updates.
