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. http://www.rithum.com/kgzmusic
