I open Coppercube and load your project. I can see the actions on the “scene” “when a key is pressed,” but when I try to add one, nothing happens. The same thing happens on a new scene. I isolated my extensions (more than 100) in a folder, leaving only this one, and now it works, so there must be a conflict on my side.
I found the problem: these three extensions. Every time I add one, the “shake” no longer works:
action_fade_D3d.js , action_pixelated_shader.js , action_rendertotexture.js
