Missing a hook to really differentiate it from its peers, but the gameplay is solid, challenging, and fun enough for what it is. At times, it feels like a training tool for working on platformer micro which can be hit or miss depending on what you're looking for out of it. Personally, I found it fun. Beat up to D15. I might continue later on, but I don't have much desire to try and beat D100, which sounds like just a fucking lot for very fucking little.
