Not so much “moves,” as it is stringing moves together and using the environment.
From what I am learning about SMART, it is more than the sum of its parts. It offers a limited amount of ‘base’ moves - mantles, vaults, slides, wallhops, slide to break fall - and on the surface they may not look like much, but when players start getting creative - stringing them together in interesting ways and experimenting with the environment, it really opens up the system.
Sadly, many people see the limited amount of moves you can do, or even the things you can’t do (flips, rolls, etc.) and write it off as lame or gimmicky, without even really knowing anything about it.
