Senso is a game where you have to repeat a random melody, that gets longer and faster with every round. How long can you follow Senso? You can also play it with multiple players by exchange the mouse with every round. I used to play Senso in the 70's when it was a brand new hardware-electronic-game, that I got as a birthday present. With the new Scratch 1.3 list-variables it took me one afternoon to design and implement it in Scratch. I used it as a test for the new Scratch 1.3 capibilities, that I like a lot. Now at 15.09.2008 it works even in the Online-Player. After putting it online today at 7.8.2008, I found out, that it doesn't work in the Scratch-Java player: There seemed to be a bug. But now everything works fine: The Scratch team found the bug and solved it.
