I love that is educational, but not in a super in-your-face way. I think you hear a lot these days of people sayings, it kind of goofy but the reason I remember this formula or concept is because it was in a game I liked as a kid. So I love that is fun with educational value. The art style is very nice. The one thing I would tweak is difficult curve. I feel like level 1 is easy, and then it just ramps up really fast.I think this is because even though the formula is only a little bigger, there are a lot more things to dodge on the screen. A good way to implement a smoother curve would be making a more open environment for the first couple of levels and then maybe changing it to tighter spaces so the player has to learn how to manage that sepeartly from a lot of guys. Just suggestions. Anyway, really like your concept and I hope your game does well. Thanks for a good playthrough.
