Rather good, original game with fluent graphics (great that there are different kinds of kernels), but I would prefer if it went chronologically, so you would know which levels you completed, which levels you still need to complete and if the difficulty gradually rose (and possibly the game mechanics slightly changed once a while). This way it's good for quick entertainment, but there's nothing to really 'achieve'.
And just a recommendation, don't advertise your game through forums. People who want to try and review new games already browse Under Judgement section and look here without being told so. This way you will most like attract just meaningless low ratings.
