Got through the levels(maybe all) with around 10 retries per level. Level obstacles are the most annoying thing in this game. I find the character control a bit uncomfortable and not feeling confident moving around the obstacles much. But the enemies and bosses are fine. And when I got through the level with boss only, the next level won't load and the screen is forever empty. I'm not sure if this is the end of the current version.
But anyway. The game does have really nice art, everything fits the style really well. The combat and boss fight are very nice. A little more easier obstacles would be better.
