I appreciate the kind words! I think we may do a few updates on this, because I too like the premise.
That bug I unfortunately caught too late. The end screen was contingent on detecting a velocity of -10 or less. The launcher goes from 0 to 100, then restarts at 0. I found if you launched with a low score, around 10, your velocity would only hit -5 or so, missing the end screen conditions.
