Uh well well
I liked the "easy" AI in the first one better... you should make some of the first ones like that. And how do you unlock secrets? For some reason in challenge mode, I could not do any damage to computers.. I assumed that was because it was BETA, but I guess not?
Also, on the attacks, it says f,g,h,u,b,n ... but U button doesnt do anything... am I missing something?
Anyway, great work, but AI could be more interesting. You could make it so that he is trying to make you chase him, but if you dont, he will come after you offensively for a bit until he gets your attention.
And challenge 2 is like.. OMGWTF..
But yeah, tons of good stuff, I just hope you really polish it before releasing it.. then it will be something insanely great.
(This would be an awesome platformer, thats what I thought it was at first... just imagine that... a 2 player platformer... probably alot more work eh? haha .. beats making complicated AI though ;) )
keep it up!
