I'd think it as a modernised version of a classic roguelike game. Because of the generated level, the difficulty can vary in parts, although in total each level seems about equally hard. If you're lucky, you get lots of barrels at the start and so you have a better chance of surviving. The game appears a tad hard for a beginner, but being well-made, it could well hold your interest long enough for you to succeed. I think the most learning the player has to do is with the attacks, especially the special attack.
