Same happened to me.
Thanks for sharing how to open the app
I don't know how, but the first time I loaded the game it showed me in debug mode, where I could select all the units and effects, both mine and enemies. Anyway, great game.
It's bugged in MacOS M1, when I try to rotate the camera it shakes and gets stuck, I tried to compile it from source but it still doesn't work :/
I don't regret having downloaded and compiled it to play on macOS, the shaders looks great, the web version doesn't do it justice.
I like the pausing and jump so fun :p
