This game was honestly better than I thought. I think the most impressive thing was probably how I really did learn from it. Well, I always knew simple math. I still appreciate how it's educational. You really do have to find some interesting combinations with this. The best thing to do is to find ones.
I didn't know you'd use factors higher than 9. There's only ten digits, but an infinite amount of numbers. I thought it was well organized. True, it's still pretty hard, but I'm glad to have played it. You guys do make unique games.
