@tabas I completely understand your point. Finding the right balance between teaching enough and keeping the game engaging has probably been the biggest design challenge so far. I'll continue experimenting with shorter text, more interaction, and different ways of presenting information without losing the educational value.
I got back on the game and I think that a lot has changed since I have visited it. It's more fun with those awards and the progress level. It's really an educational game. I am sure that there's more in store for you to develop this game and what you need now is more exposure or even maybe making this an app because most people are in their smartphones. They can play this while they're bored or waiting for something.
