Here is the link to my prototype.

[Apocalipsis]

Ok, since it seems people are way too lazy to download something of less than 500kb, I'll upload some sprite sheets: (But seriously, download something like that takes seconds)

Ok then, I don't really know what you were trying to do here.
Why it's called Robo Ninja? I don't see anything related with "Robo"...
Most of the sprites are just half-erased rudolf sprites. (Except for the dragon punch of davis, I don't really know what's that either...)

Still, I didn't tried it in the game. Two reasons for that.
First, you have a wrong name folder: "syn" in place of "sys"...
Second, a char without standart-quality sprites is nothing to me (It would need to have the complete awesomeness in dc, but you said you were better spriter than datachanger, so...)

Now you can said it's still a prototype. But this must be like ver -0.5.
There is no reason to show this, if you need to complete with mechanic parts the parts of rudolf that were erased, then do it before showing it. I'm sure anyone can do this in some minutes.

(I'm not trying to offend you or something, but you told us to comment what we don't like, and I'm doing so)
