I'm going to be the most specific about this. I tried to ask help on 4chan and reddit but nobody knows anything about that game. First of all, I'm from Mexico so I played educational games because schools teach English language. The year is 2006 or 2007, I was 7 years old on Waldo's Market, a cheap store where everything was at the same price. There was a section with different softwares and PC games, very strange games. I was interested on a Math game with a slighly damaged box. My parents bought it and when we arrive at home and put it on the PC, it was a different game: an English language game. I didn't remember the name, the disc hasn't any logo. No manuals, no garantee letter, anything. My mom supposed that the original Math game was steal and later replaced with another disc. Anyway, I liked the game because it taught me a lot of vocabulary. I clearly remember that the protagonist (and the archetype for every character) was like this drawing.
I know, he looks like Doug but I'm very sure that this is'nt a Doug game.
The game contained differents scenes for different words like a school, a street, a house, and even a Prehistoric-era. After one or two years playing this thing I lost the disc. So everytime I tried to play this game without the disc, a window like this shows on.
On 2009 my old PC was formatted because a virus, everything that hasn't saved was lost, the game files included. Since that date I never seen the game again. No information or screenshot is on search pages. I hope that my poorly Paint drawings (and my broken English) help with this personal searching.
