Well, I played it.
I get 60 fps most of the time, but I got a few lag spikes here and there where it would drop to 30-40 fps.
I absolutely despise the menu, I just don't see how it can be comfortable using that.

I suggest using some sprites with some nice images.
Character movement feels solid, perhaps a little bit too slow. If it were me, I'd speed up to about 1.6x the current speed.
The camera can be rotated right around until it's upside down. You should add a limit to x rotation.
The advertisements... Just... Why. Are you forced to use the or something?
I see you turned the particles blue, so I can't call it the "super sonic period man" anymore... I suppose it's now more of a "Masturbating Madman in a box" game.
All in all I can say it has potential of becoming a good shooter, but it needs a lot of work. I hope I wasn't too harsh, so stick to it.
