Indiana Jones, Rambo, and others ended up in 1980s Czechoslovak text-adventures

Any horse people can see from the art that something is a little off. The riding style, even the horse, is European. No america studio would have Indi riding like that with his knees all bent into high stirrups. He would, he did, ride like a cowboy.

Note the different stances of the three characters. Indi and his father are on western saddles.

Interesting article, but it's strange that Indiana Jones in Wenceslas Square and the game where you have to burn books to "emit the light of progress" (!) are website conversions that bear no resemblance to a ZX Spectrum game and have made up "loading screen" graphics, whereas every other playable game[0] from the period has a screenshot from the game and plays the Spectrum code directly in browser.

Edit: These seem to be proper Spectrum files for the games (for playing in an emulator):
