The game is pretty interesting, the graphics, intro and audio is really good.
a couple of bugs I found were this:
when moving forward and shooting player goes up for no reason, and can basically fly
the souls can be easily missed, ruining levels.
the player shoots in the direction its walking, not the direction its aiming, so its really hard to fight.
overall, its a good game, and with some more polish would be pretty interesting. Nice Work :D
