A major improvement from Access Code: Heaven. Difficulty wise, this game was much more balanced, and I thought the atmosphere is what made the game work. It was strange because at some random times, the music would cut out, so if that was fixed, I would probably enjoy the game a little more. Once again, it's still a pretty short game, but the structure and story made it much more interesting than Access Code: Heaven. The bosses are a little better here too. Still could be a little more interesting, but once again, big improvement.
Keep it up!
