Review :
Theme
Good theme, there is not a lot of parkour with a "Music" theme, and any "Trumpet" one.
Build
Pretty good build, the build fit with the theme, the build looks good, the only thing that I'm not a big fan (But it's only me so eh xD), it's there is some floating jumps around the build.
Parkour
Good too, there is a lot of variation of blocks, it's not repetitive, fit the easy difficulty and there is a piston head (Nooooo, I didn't put iiiit c: ), then good parkour !
My opinion
Gonna be accepted, there is no "big" negatives points, it's a simple parkour with interesting jumps ; good !
(For people who asked "Why did you this review ?", because :
1- I like doing review (Even if I'm lazy)
2- Ask fishy c: )
