@elizabopolous: thanks for the feedback! Yes, the every little effort at the end gives much more points than at the beginning. The idea why I made it as it is: I thought it would be good to start slowly to get the player in the right mood for later, and also to allow the player to look for the optimum in disconnecting the creats. Later on, as the tempo changes, the disconnecting gets less optimal, but the player gets more points due to the level multiplicator.
AWESOME... first kreds donated by grrr1313. Thanks a ton! And you have to consider that he's from Serbia and I am originally from Croatia. A big step in bilateral relations. (just kidding) ;-)
I've added the leaderboard. 110,107 my best at the moment.. It looks like playing with the mouse is more difficult than on a touch screen. Let's see how the top scores will be, then I'll be considering some adjustments on the structure speed.
