Frozenbyte announces the release of a beta of the Frozenbyte Editor, which will allow the creation of custom levels for Trine & Trine 2 (thanks PC Gamer). Here's word on why they've held off on this release, which cautions users that this may involve some difficulties:

You read correctly! We’re finally releasing our Frozenbyte Editor for both of the Trine games. As we did with Trine Enchanted Edition, this first editor release is a public BETA, and will be behind a password.

The reason we’ve held off releasing the editor to the public before has been quite simple. It’s pretty difficult to use if you don’t know what you’re doing, and there’s *very* little documentation or tooltips.

So did we make an easy-to-use version for everyone to enjoy? The answer to that is…not really :) Instead we’ve opened a wiki page at www.frozenbyte.com/wiki and provided some very basic instructions on how to use our editor. It’s an open wiki after you’ve registered, so anyone can edit and post information, and we hope that people will start to share their knowledge with everyone. We’ll also be updating the wiki ourselves and tracking that all the instructions are correct and up-to-date.

The Frozenbyte Editor is a very diverse tool. This is what we use to make games like Trine and Trine 2, and it’s based entirely on our own technology. You can now edit existing maps, make new maps and do all kinds of things with it. If this sounds like fun, go a head and play with the features and experiment!
