I just read jonbro's review and couldn't disagree more, though i think it is a good, reasoned review.
first of all, as he already mentioned, the concept is very original and turns the basic jump and run into something... larger, which is innovative but carefully thought out and fun to play.
but i don't think that precise mouse control corresponds so badly with fast arrow key movement (just take call of duty, battlefield etc. for example). in this game, just a little reorientation is necessary, and i am truly sorry if one can't manage that. i din not find the controls too slippery or sensitive, i made it through each level without any control-related complication (though it took me some tries) and did not even come across one of the mentioned bugs.
the overall game and level design really pleased me. the colors match really good, the comments at the begin of each level are hilarious and the secret levels are hidden quite intelligently. keep it up!
