First off, the most obvious one, animation. Nuff said.
Second off, try a bit harder on the art, I mean your character was standing in the most awkward position...
Third off, you should of been able to learn new moves to give a wider choice to the player, besides the stats, your pretty much playing it out the same as the next guy.
Fix those things in the sequel and we might just have a good game.
So I just played, and it's not that bad. Well obviously like others said, animation, haha. Other than that it's pretty fun, it just needs a slightly better story line. Keep working on it and good luck with number 2.
its kinda cool except i hated when u say u wanan fight the ninja and u die and have to start all over+the animations need to be better but overall its a good, fun game
