Really good work. You've turned one of the most boring things in the world for kids, multiplication drills, and made it something they would actually want to do.

I liked the way you introduced the equations, gave the answer and some controlled practice before getting them to review the previous equation and drill the new one at each stage, until the final battle when it all came together. You effectively merged common game play progression with typical teaching methodology.

The levels were simple and attractive, with new elements added at each stage to keep it interesting to see what was going to come next. I especially liked your turning platforms. How did you get the model to stay on them?

A couple of bugs. The camera goes through walls in places. This is hard and some AAA titles have the same problem. It wasn't too bad though, I was trying to make it happen. Also, Once a spider jumped over the rail (I think I accidentally kicked it) and it went walking around in space where I couldn't get to it.

I would have liked to have seen more different monsters on each level. I know there is a budget for time and money, but if you can get more of either, then it would be nice.

My last crit, when the escape key is pressed, you could add the option to save the game.

Anyway, great game, very professionally executed, and I hope it does well.
