One of the best games of NG. The first one was a classical, simple, yet awesome game. It was one of the simplest and greatest games of Newgrounds.
This one, however, upgraded EVERYTHING from the previous game, and this game can par the likes of Madness: Project Nexus. The only bad side is the same of all of that kind of game: Once you reach a certain level, it will be always "go down, explore, level up, get items and go back", all way around.
But it never gets old. There will be almost always a enemy tougher than you, and when you re-start the game from the beggining... You can do everything again, but in a different way! The cave resets and never haves the same layout of before. As I said before, the only reason that I don't give you a full 10 (However, I will give you 5 stars), it is because, later, you will be always repeating the same thing. But it is a normal flaw of that kind of game.
9.5/10. Congratulations :D
