(Developer) A very helpful user, Alan Wolfe, has just tracked down the keyboard problem some people have seen in Solarian II. It is an incompatibility with iClock; iClock is eating keystrokes that should go to Solarian, and that messes up the game. Just quit iClock before starting to play. It is possible that some other "background" software might cause similar problems with Solarian; if anybody finds any other examples, please let us know at Stick Software. Thanks!
