Good...
I enjoyed the game to a point. The problem I had with it was that instead of just getting harder, the levels got longer. I'd have rather played a game with a bunch of short levels with one challenge each that gets more difficult as I go; instead I would play an entire level, passing a few difficult traps until I press the wrong arrow or make a little mistake and I'm sent back to the very beginning. Frustrating.
Overall, not bad. If there's an impossible 3, I'd suggest making the levels shorter and base it more on ingenious setups of traps, for example the smaller spinning logs on level 8 just after the first big one. If that was at the very beginning of the level, then I'd have been more motivated to keep trying; as it is now, I just gave up because I didn't feel like doing the first part over and over again.
