Bloons Tower Defense 3: Hard, Track 4, Lv 4-54

This is a video of me, Tasselfoot, beating Track 4 of Bloons Tower Defense 3 on Hard. Because of length, I had to cut out the first three levels. Video is still on 4x speed. Beating the game is clearing level 50, but I continued until 54, where I basically gave up instead of laying down a large tack field.
