The game was really funny and i really like the art style of the game.
Yet, the keys i need to use always change and it makes it hard to move around at all or if i'm in a battle. It's just a thought, but maybe add a left-hand /right-hand switch? Like i would be moving around better and in battle too, if i can have my moving controls be w,a,s,d and use the arrow keys to shoot.
Also i don't know how it is over at your place, but my z and x are so far away from each other, i would prefer using r or space button instead. Yet again, it's just my opinion :)
Other than that, i really liked the game and i really want to see more of it!
