Hardly worth it.
A great, very interesting premise that got wasted on howlingly bad controls (this *could* have been be forgiven, as this is 7 year old flash) but that difficulty curve over the roof that completely ruins experience. Most of that difficulty wasn't even needed (much less forgivable). Coupled with 7 year old not very responsive controls, you get a bad experience overall.
The excessive difficulty made me quit the last level. After checking the walkthrough, I was certain that the last level isn't even worth playing anyway.
A tip: Playing your own games isn't a good way to test them. Consider sending earlier copies to friends and relatives (those who are into gaming at least) so they can test before release, and value their feedback. There isn't enough common sense in the world to tell you that that last level isn't even remotely fair nor funny. If you did so for a different target audience, you should have explained that - and expect them to give you better reviews.
At least music is okay.
