To bad i will start with a negative comment, cause i really wanted to like the game, interesting gameplay, nice graphics and sounds. But i'm not gonna play it anymore cause the community is full of haters and flamers.
It was my first game of this type and i never played the Warcraft III mod "Defense of the Ancients" so i consider myself a noob. but thats not sufficient, if you are a beginner, don't even bother looking for servers labeled: "noob", look for "mega noob" or "ubernoob" servers but even that wont safe you from getting insulted because of "wrong" gameplay. If you want to give it a try, take a friend along, after all its free at the moment.
A very usefull site to begin, with explanations of some basic and advaced gameplay-elements is:

It is nice game that makes you think. Some levels are quite hard and you have to try them many times untill you find the right way. Game is great, has lots of levels to discover. I have let my nephew play the 'kids' levels and he liked it too, played 20 levels in a row (then he wanted to play some racing game

If you play whole game, you can try another game - "Professor Fizzwizzle and Molten Mystery" which is quite the same with new levels and new features ( fire gun, teleporters, fly-bots ).

I played Linux and Windows versions and its the same on both platforms.

Hey,

Submitted games are published by administrators, usually in a couple of hours after submission.
It also takes some time until new content is indexed by the search engine.

Cheers.

There is a big problem to make it possible for all users to submit changes. the current implementation of the image upload procedure prohibits the possibility to use drupals build-in revision system.
With the revisions all users would just post "changes" to the current game page that could be easily redone by moderators.
That said, it will take some time before this can be implemented. Not expecting that situation i'm very unhappy
