I am from India, & I still remember back in 1998, my uncle had a motorola pager http://goo.gl/Ziuy34. When i held the pager, it was cute & fun little device. If we think of communication back in the 90s, I wish the present would be same as the 90s. :)

Call the operator;say your message;& wait for the person to call you.

The game is simple/hard and beautiful.

I am just curious. What engine and development tools did you use? If I like a game, I want to know the backend tools that was used for developing.
