Wow... Just, wow! I love so much of this stuff. The cliff climbing, the enter/leaving level transitions, the (somewhat) realistic bombs, the new graphics, the holes in the walls. Wow. Too bad you won't finish this, as this looks more realistic and professional than anything I've seen in... ages(ever?) on graal.
EDIT:
Hell, I could even pay for another 6 months on your server if that would motivate you to keep on working on it.
