Bloons Tower Defense 4 Walkthrough - Track 1, Hard, No Lives Lost (Died on Wave 79)

This is a video of me, Tasselfoot, beating BTD4 (Bloons Tower Defense 4) on Hard Mode, on the "Beginner" Track, Track 1. I beat all 75 waves without losing a life. Went on to die on wave 79 (lost all 100 on that wave). I started out at Rank 20 and finished at Rank 25. Video is on 4x speed. I thought I had muted the in-game sound... so, I apologize for how bad the game sound effects sound at 4x speed. That's why I added the other music, which is by my friend KgZ.
