What is the significance of the  "wave 902" text appearing next to the #1 score in easy #7? I thought that only the last level within each group could be played in endless mode. Also, in Revenge of the Eye, I'm in #3 at 54000, whereas #1 and #2 are at about  7 and 8 million. There are 10 waves and my multiplier was almost 300x by the end (about 100x after the first few waves How is it possible to increase the multiplier to the extent that would be needed to get those high scores? Are these just Open Feint glitches?
