@I wish I realized that sooner. I got 100 gems for 100 kreds, then I realized that I couldnt get beta. I sent an email to chris but he didn't respond. :(
Guys, Kongregate is only hosting the game! If you want to be heard, ask Chris Benjaminson, the creator of the game. You can email him (I think it's chris@everybodyedits.com) or post a comment in his blog. Even then, he still has his limits. He can't just instantly click a button that says: "add a spot for people to edit themselves." And as for free chatting, I do agree with that, since anyone who has been on a free world has obviously been exposed to curses spelled by blocks.
Perhaps a good feature would be something that automatically selects a block type that has already been laid down by doing alt-click on it or something. It would work better if there weren't beta-only blocks.
There's an ending 3/2. If you wait in front of the last beam after killing the boss, that one will dissipate too, and then you can jump over to the special level.
