Friend tried to register today. Finished a game level to prove non-spambotness, then got the following message:

Warning: strlen() expects parameter 1 to be string, array given in /home/hacker_apache/html/hacker/html/util/gamebase.php on line 87
invalid looking level

Anything he should know? Thanks.

You can beat "crossflip". however something must be done about it, since none can proceed with the puzzles...
