Someone needs glasses... He doesn't flail his arms around a lil bit, he really slashes them like really hard... Plus its range is farther. Maybe he could damage 2 enemies at 1 time if he was close enough to 2 enemies...
The alpha's combat system is clearly different though; it has a few different mechanics to it than the release did. The slashing's hard hitting feel has to do with the framerate in which theyre rendering the sprites; its all the same, theyre just cycling it at a different speed to give a different effect to it; if you take a look in the sprite rips from CT; all of those animations are in Cronos sheet, and theyre all used in the final release; they're just not as... preliminary as the alpha is showing lol sure its cool how they utilized the animation cycles for the attack, but just didnt feel it worked for the final release *shrugs*... You could heck the rom and make that particular animation for an attack if you feel its necessary to make CT worth playing
but I personally think CT was complete within itself lol
As for the rumored 8th character; its just that, a rumored character. Just because there was some left over junk data in the outworld player set, doesnt mean theres another character. More than likely what happened was; judging by how active the world map appears in the alpha, they probably had people walking around on the map, or maybe map-related events that require NPCs or something, and thats why theres that extra sprite set. It was probably never obtainable by the player to begin with.
Chronos development was rocky, but not as rocky as Seiken Densetsu 3 :p... but I heard they had quite a few troubles with it. 1999ad is kewl to fly around in too btw, but its really... really buggy lol
