Really liked the premise but after like 20 minutes of trying I couldn't even get past the 30 second mark, maybe just a skill issue on my part. Great presentation too.
Btw godot can't really sync the mouse position you get through get_global_mouse_position with that of the OS. Updates only occur periodically so if you were to implement a software cursor using a sprite it'd lag behind the actual cursor and I think this may be what's happening with the bricks here, making them even harder to catch.
