Bug report: wait for a 4-block line, move it to the far right, and hit Up to rotate. The game first gets the piece stuck then decides that's where the piece is going to sit. Report 2: the arrow keys control the game _and_ scroll the page. Edit: My brain isn't fast enough for this D: Anti-kudos for making pause hide the grid, so I can't spend time staring at it GRR :P
