This is just great.
Intro/Outro: I, for one, love the high-pitched sound. And the ending is pretty cool too.
SFX/Beats: Nice high tempo you got going there, like how the sound alternates from side to side, and of course, the odd squeak, very nice.
Other: Well, really no "progression" with the song till bout' 2:33, a small intermission, but hey, love the repetitive beat.
Conclusion: This is the kind of thing I stay up till' what time is it now, 3:56? Well, anyway, this is what I stay up most of the night to find, and while others don't understand, I do find nice jewels of internet finds, including this nice little beat. Thanks for making this bro.
