Gametrailers.com - Savage Moon - Pax 2008: Debut Gameplay (Cam) For a tower defense game, it looks pretty cool. Might make a nice companion piece to Pixeljunk Monsters.
The in tower footage was awesome, but other than that I kinda feel a bit "meh" over it. Looks good, though, which is a plus.
The in-tower footage was what sold me. Level layout and the ability to quickly pick up and play are keys for tower defense games for me. It's why I like PJM so much (even though the later levels are hard as all hell).
Later levels? I can't get passed a lot of the early ones ¬_¬ At least not with rainbows, which irks me.
The only medium one I can't beat at all is the one with only 4 trees. I'm doing my best to try and beat the hard levels, but those fuckers are tough. I've got, I think, 8 rainbows right now.
