Dropping a comment here for anyone else who will play this so:
get as many points as you can by getting the blocks placed and them going through the holes, (hitting the red wall will give you minus points) its meant to be a endless game. But you can loose by getting -100 points in the grave which is Total points - Time passed. the game also gets faster and faster so good luck.
In the future I will try and add a tutorial or make it more intuitive :)
