Just one thing: It isn't to scale.

I knew that, If I make a tiny cannon you'll would tell "too small for his strengh"

Yeah, but you could at least make it a bit bigger. Maybe about as tall as a dreadnought and proportionally wider?

I gonna do a bigger version, but this idea its pick up a mega-crab and make it look like robocop, rebuilded.

Just how does this balancing work?

Anyways nice sprites, maybe add a bit more types of crabs.

I'm assuming this crab has a weakspot that we can attack for Massive Dam-

*is socked*

Nice spriting!

Looks kinda cliche, crab with a gun, but I'll try it out.
At first glance: Too much black, and its too dark to look like its out in the sunlight.

ehh.. looks alright.
But maybe lighten the colour a bit.

The gun just needs some kind of counterbalance sticking out of the back of it. Right now it looks weird that its attached at the very back end.

And it could be smaller. Don't assume what our complaints will be.

dragonxp@ : When you tab Z the crab rotate a bit to left and when you tab X the crab rotate a bit to right,
Its very useful and funny when you want to use it like a metal-fling-hammer, overpowered well used.
About making it more light, I disagree, many users hate shiny sprites until puke...

Fat Zombie@: jejeje... yeah keep dreaming, and thanks ^^

CrazyMLC@ : well, It is a cliché, but I like classical things, jeeps with guns, crab with guns, and butter on butts.

Darlos9D@ : I have to agree, I can sprite almost everything but I don't know what sprite for this one...
that's why the gun looks like a potato cannon...

Shiny is usually better... as least in my opinion. Not like I can force you to do it, but I'd recommend giving it a try.
