Came back to this because of the Badge of the Day thing, and the controls seem awful; stupid keys sticking and having me run into spikes, jumps not happening, etc. Was it always like this? I remember a game that actually worked back in 2008.
For those of you having trouble, the going right comment is the best advice you can take, and then just take as much time as you need.
For the 2nd half of the game, don't dodge the stream of 'stuff' every third go like I've just been doing - instead of being a giant death laser, its a load of guys you need to save.
D'oh.
