There's a cheat code to unlock everything. I added it at the beginning of the movie
! Version info: libTAS version: 1.3.1 ! Annotation info: {{Game: Towerfall Ascension + Dark World Expansion v1.3.2.0 DRM-free x86_64 version (taken from Humble Store: https://www.humblebundle.com/store/towerfall-ascension and https://www.humblebundle.com/store/towerfall-dark-world-expansion . Dark World Expansion DRM-free version is noted as Windows only, but works for all systems because it is just an archive of data files to be placed inside the game directory). OS: Ubuntu 18.04 amd64 with Linux kernel 4.13.0-36-generic, libTAS v1.3.1. Before the movie can be played, the game must be launched natively and fullscreen mode must be turned off in the options. This is needed because libTAS enforces a windowed mode, and some games like Towerfall does not display correctly if configured in fullscreen mode. Inside libTAS, fill the Game executable to "/path/to/game/TowerFall.bin.x86_64", then open "File > Executable Options..." and set "Library path" to "/path/to/game/lib64".}}
