Oh this project, I have been seeing it on and off on a retro games site.
It does indeed look like an Indiana Jones game.
Another game that has an Indiana Jones theme is Joe Gunn which was released some years ago.
It did not look as nice as this one though.
On that same retro game site the conversion of Indiana Jones and the Last Crusade adventure game was also shown.
Had I known that people here would have been interested in such projects I would have mentioned it.
