This is really fun! I'm interested to see how well it would translate into a purely physical game. The cards would be easy enough, and swaps/hp could be kept track on a piece of paper. However, I'm curious how the values at the top are generated. Is it a simple random number 10-20, or something more?
Thank you very much for the kind words! :)
The numbers are weighted a little bit depending on which one has been generated before. So basically a total value is generated first that doesn't surpass what you could reach with all cards from 2-10 revealed. Then up to 50% (randomly) of that total is assigned to one of the three values (chosen randomly), then up to 50% of the rest to the second and then the rest to the third one.
