A sandbox game! Cool, I wonder what I can do with this.
Let's see... Fight "sheep" which aimlessly walk/jump/fly at you through walls, without any sense of AI: I've seen better sense of AI in chess.
You can't place or move any blocks, or even edit any levels at all, unless you're editing YOUR own level, and there the sandbox genre was gone.
Blocks, All blocks are basicly the same thing, with a paintjob. Sand doesn't feel any more different than a block of Plastic.
Kongregate, I'm upright disappointed. :(
If you don't want to break your mouse, you can press any keys on the keyboard to shoot! Found that out after about 2300 seconds of furious mousetapping.
