Started to play a different way after I realised it helped me being MUCH faster and improving my invisible play skills. I used to play with my eyes permanently jumping from the playfield to the next tetromino field when I suddenly realised last week that those short eyes moves might very well make me loose a lot of time. So I started to play focusing only on the next tetromino field and doing, surprisingly... not so bad ! It's still very hard to focus and get my eyes not moving everywhere and, of course, I need to watch the playfield again when I misdrop or do big mistakes but I really feel like I can push up the speed to a level I couldn't imagine before. Anyone here playing this way ?
