Wow, looks like Round 26 is the new highest round anyone in the comments has gotten! I feel like the Blast Off + Uno/Zwei/San combo may be a bit too overpowered…
Yep, the game is endless. I originally intended it to “end” on Round 15 before going into endless mode but that didn’t happen. And I definitely will work on a better tutorial as that’s a common issue people have with the game.
