Played a short run and thought this game was simple, turns out the game has much more into it. I ended up with a 2100-ish score in the extended run, which I somehow still managed to get 1 or 2 rounds in the latter half correct by remembering the numbers instead of directly calculating them as they traveled down.
Overall a clean and polished game, I can see myself going back to this when I’m better at math (hopefully).
