Two hundred and eighty one, that's the number of times I died when playing this game. It frustrated me beyond belief, but it was still fun and felt rewarding when I finally managed to beat it (in spite of the anticlimatic ending). Aside from some control issues, the challenge felt legitimate and fair at (mostly) all times.
This is your everyday action platformer, with regular jumps, wall jumps, a plethora of obstacles, and a mostly linear path to the end. It stands out, though, due to pretty good level design and the overall sense of scale we get when we see such large chunks of the game at once. It maddened me and made me punch my keyboard in frustration, but it never bored me nor made me feel like my deaths were unfair. If you're into these nearly masochistic (but still fair) games, this is for you.
There are a few issues with the controls, though. In particular, with the jumping response time. Very often did I fall into the lava due to not being able to jump because I pressed the jump button too close to the edge. That frustrated me more than it should.
Also, the wall spikes are often too hard to see if you're not a person with perfect eyesight, which led me to die more times than I should due to simply not noticing the wall spikes in time.
All in all, though, this is pretty good.
