Well, to be honest, some ideas are still ridicolous in either good (Weegee, Porky, Duck Hunt Dog, etc) or outright horrible (Goku, hands down) way and the whole thing sounded nearly impossible to do with the amount of characters listed. It must still be very hard to do since it is still a demo version after nearly six years. It would take even longer if they would pay more attention to sprites, like SSF2's developers. Last one is something that really needs to be fixed.
Is it just me or controls on keyboard are really unresponsive? I can't do what i want half of the time (i use NAir instead of FAir, jab instead of side tilt/smash, etc. most of the time). It works fine for SSF2 and Project M.
