Thanks for the kind words!
The actual score is indeed influenced by the random points of the enemies... but not sure if I will keep that in, in a next iteration. It was fun for the jam - but not really enough for the core gameplay.
And yes, I also would love to include a highscore-list ... at least local, but would be awesome to just have it globally ... who got the most enemies killed, stayed alive the longest (timewise) or who just made the most points.
So yeah, in a future iteration I will (hopefully) add this ^^
