This update (4.6) fixes several minor things:
Balance fix: Some powerful orbs appeared too frequently on the Crossroads, which allowed the best players to harvest Hyperstones too easily. (This should make the game harder only for the best players.)
Achievements should pop up immediately now, and also F12 no longer disables the intermediate scores (so you can make a screenshot of them).
A new leaderboard has been added for Orbs of Yendor.Have fun!
