I've got some 14 levels I'm throwing together right now. Should be up before Wednesday. Don't nearly have enough time to try and make a campaign, but I'll make do with maps. I think there's some pretty fun and challenging ones in there. And in case you were wondering, I won't make a new thread to upload them, lol.
In the meantime, check out some crazy Lugaru textures. They make the game look pretty messed up and cool.
And please consider playing some other maps I made. Feedback is welcome.
