Video doesnt showcase how the Beep Beep blocks work. I have the project also and doesn't tell me lol
Use the BeepBlockBeeper component. (Create an empty Game Object, and use the Add Component button to add the BeepBlockBeeper component to it.)
I LOVE your engine, I'm thinking of using it for my 3d platformer eden's blade, an original game, I came here because i want to monetize my game using your engine and I was wondering if I could get your permission
