As in the Esklavos games, you have an option of playing it in English or Spanish. Playing them in English provides numerous opportunities for language-development since many items are given text labels.
This Halloween game is so new that no one has yet posted a “Walkthrough” (the instructions to win). As I’ve described previously, English Language Learners playing these types of games with walkthroughs maximizes their use for language-learning. However, even without it, this game would be good for ELL’s. As soon as I find one I’ll add both to my website under Word and Video Games.
I have, though, already added the game to The Best Websites For Learning About Halloween.
