Great job designing the playstyle of this game! I love how the cards interact with each other and it isn't hard to find combinations that you personally favor, for me that's definitely Rat/Rat king/River. I'd love to see an algorithm added to allow the game to continue indefinitely, progressively increasing the total required for victory but I understand that at a certain point rats and blood river are the only way to win. A larger board or boards with obstacles could be fun but overall, great game and I look forward to seeing future development if there are plans as such!
Thanks for playing and for the kind words!
Funny story about the infinite mode. That was how the game worked until like, a week ago! The problem with it, as you anticipated, is that if the game goes on forever the only good strategies become the "exponential" ones. We like having the balance of more "linear" strategies being viable as well. Maybe we'll add it as an option at the end later!
Larger boards and boards with obstacles are definitely something we've considered, as either "characters" or "ascensions" - we're trying to get in the core tiles first though.
